An Airtable-style spreadsheet interface directly on PostgreSQL: Teable is an open-source no-code database where every table is a real Postgres table. Unlike tools that store records in a metadata abstraction layer, every Teable table is a real Postgres table with standard column types, so filtering, sorting, and grouping run at database speed, million-row tables answer complex filters in roughly 200 milliseconds without index tuning, and any PostgreSQL-compatible tool - psql, BI dashboards, ETL pipelines - can query the same data directly. The interface offers Grid, Kanban, Gallery, Calendar, and Form views as non-destructive overlays with their own filters and hidden fields, plus 20+ field types, formulas, comments, attachments, batch editing, undo/redo, and edit history. Collaboration is real-time with live cursors and instant sync across views, backed by Redis, and a REST API is auto-generated per table, largely compatible with Airtable API clients - alongside native SQL access for BI tools, analytics pipelines, and your own applications to JOIN and query directly, with no exports, API rate limits, or sync jobs. Global search spans all records, chart plugins handle quick visualization, and CSV and Excel import/export cover migrations. Where Airtable caps paid plans at 100K-500K rows and charges roughly $20 per user per month, a self-hosted Teable instance has neither limit: the Postgres database itself is the export if you ever leave. Built in TypeScript with NestJS, deployed via Docker with PostgreSQL and Redis, and licensed AGPL-3.0.

Mathesar puts a spreadsheet in front of your PostgreSQL database, letting anyone on the team browse, edit, filter, sort, and query tables without writing a line of SQL. Connect it to any existing PostgreSQL instance and immediately navigate schemas, tables, and records through an intuitive grid interface with inline editing, grouping, and summarization. The query builder joins tables across foreign key relationships, creates custom views with aggregations, and exports results to CSV. Rather than inventing its own permission layer, Mathesar maps each user or team to a native PostgreSQL role with granular schema-level and table-level privileges enforced at the database engine level, so there is never a gap between what the UI allows and what the database permits. Record summary templates display human-readable representations of linked records, making foreign key relationships immediately understandable instead of showing raw IDs. Import data from CSV files, create new tables and columns with proper PostgreSQL types including arrays, JSON, and custom domains, and modify schema structure through the web interface. Mathesar scales as well as the underlying PostgreSQL instance with no artificial limits on database size or complexity. Maintained by the Mathesar Foundation, a 501(c)(3) nonprofit, with a permanent commitment against vendor lock-in or licensing changes. Docker deployment connects to existing PostgreSQL instances or a bundled database in minutes. 5,000+ GitHub stars. GPL-3.0 licensed.

CRMs, project trackers, inventory tools - NocoBase is an open-source no-code/low-code platform for building business systems like these. Its architecture is data-model driven: you define collections and relationships first, then compose any number of interface blocks (tables, forms, kanban, charts) on top of the same model, so data structure is never coupled to a particular view. The core is a microkernel where every feature is a plugin, WordPress-style; you enable official plugins, install marketplace ones, or write your own as npm packages with server and client parts. Data sources include the main PostgreSQL or MySQL database, external databases, and third-party APIs - so you can build admin panels over existing production data instead of migrating it. Built-in infrastructure covers role-based permissions down to collection, record, and field level, workflow automation with approval steps and scheduled triggers, and audit logs; a one-click switch flips between usage and configuration modes. Because custom features live in isolated plugins with a documented lifecycle, core upgrades do not overwrite your customizations, and swapping UIs never requires data migrations since interfaces sit on independent models. Written in TypeScript on Node.js, Koa, and React under the AGPL license, it is light enough for one person to run and extend - and where no-code SaaS platforms charge per seat and per app, a self-hosted instance runs unlimited applications for unlimited users at hosting cost alone.

A project brief and the task board tracking it belong together, and Litpage keeps pages, databases, and team discussion in one self-hosted workspace instead of scattering them across subscriptions. Write in a block editor with 41 block types, a slash menu, markdown shortcuts, drag and drop, mentions, equations, and highlighted code blocks. The same data becomes a table, board, list, gallery, calendar, timeline, chart, dashboard, feed, form, or map, with typed fields, formulas, relations, and rollups underneath. Automations and buttons turn those databases into working tools, while templates keep repeated projects consistent. Teammates edit together live, comment, suggest edits, and revisit version history, with page-level and field-level permissions deciding who sees what. Pages can be shared publicly or published as sites, and Markdown, CSV, HTML, Word, and PDF files import into the tree. Optional AI runs on the provider and key you configure: chat that searches your workspace, custom agents on schedules or triggers, writing help, database autofill, and meeting-note summaries. Administrators get member and guest management, security policies, an audit log, analytics, passkeys, and two-step verification. A REST API with personal tokens, webhooks, and an MCP endpoint open everything to your other tools. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Marfa is a data layer you run yourself, where your notes, tasks, reading, and records live in one typed store that any app, script, or AI agent you allow can read and write. You decide what kinds of things you keep and how they connect, and the server checks every write against that structure, so a task, a book, and a person stay linked instead of scattered across five apps. Connectors pull in what already lives elsewhere, from GitHub repositories and issues, Todoist tasks, Readwise highlights, and RSS feeds, each writing under its own type with its own key. Keys are scoped, so the script that imports your reading list can never touch your tasks, and every change flows back out through a live event stream and full-text search. The marfa command line writes and reads from scripts and agents, the TypeScript SDK builds web apps on the same API, and the Swift SDK keeps an offline working copy on your devices that syncs its writes when your instance is reachable again. A folders command mirrors your notes as plain Markdown files on disk. Everything sits in one SQLite database and a folder of files on your server, with container deployment that streams backups to your own bucket. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Define a DocType in Frappe and the framework automatically generates database tables, Python ORM classes, REST API endpoints, form views, list views, and role-based permission rules from that single schema definition. The meta-driven architecture stores schemas as database records, letting administrators add fields, reorder layouts, and modify validation rules through the browser-based Form Builder without redeployment. Server-side Python controllers handle business logic through hook-based lifecycle events while client-side JavaScript manages interactive form behavior, with WebSocket connections providing real-time updates across sessions. The built-in workflow engine defines document state machines with role-gated transitions, email notifications, and conditional action visibility. Pre-configured Desk views include list, form, report, tree, kanban, calendar, and dashboard layouts with drag-and-drop workspace customization. The report builder generates grid reports with configurable columns, filters, grouping, and chart visualizations from DocType data or custom SQL and Python scripts. Background job processing uses Redis queues for email delivery, data imports, and periodic tasks. Virtual DocTypes connect external databases to the framework's UI without data migration. Docker deployment via frappe_docker provides production-ready Compose configurations with MariaDB, Redis, Nginx, and worker containers. The foundation powering ERPNext, HRMS, CRM, and Helpdesk in production. Over 10,500 GitHub stars. MIT licensed.

salt.md is an open-source, self-hosted workspace where your team and its AI agents work on the same documents and databases, under the same permissions and with the same history. A slash-menu block editor handles checklists, tables, callouts, columns, code, diagrams, and embeds. Page links, backlinks, and a graph view show how pages connect. Any page can become a collection with typed properties like select, date, person, relation, rollup, and formula, shown as a table, board, list, gallery, calendar, timeline, or form. Ctrl+K searches titles, body text, row values, and the text inside uploaded PDFs. Two people can type in the same paragraph at once with live cursors. Comments, page history, and an activity log record who changed what. Publish a page as a read-only link with an optional password and expiry, or hand people without accounts a form that adds rows to a collection. Agents connect over MCP with 33 tools for searching, writing, building databases, and commenting, using tokens scoped to one workspace or read-only. Signed webhooks, iCalendar feeds, and Google or Microsoft sign-in link it to the rest of your stack. Import Markdown, ZIP archives, or a Notion export, and export pages as Markdown, HTML, or PDF. Use it for handbooks, meeting notes, project boards, and a knowledge base your assistants can read. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Spreadsheets and old Access databases give way to custom business apps that a team builds itself in a browser with Saltcorn, a no-code database application builder. Tables hold related records with typed and calculated fields, and CSV files import straight into them. Views start from patterns such as list, show, edit, filter, kanban, calendar, gantt, map, and chart, then take shape on a drag-and-drop canvas with a layers tree and desktop, tablet, and mobile previews. A view can embed another view, so clicking a row narrows the others and builds a cross-filtering dashboard with no glue code. Triggers react to row changes, schedules, logins, and API calls, while visual workflows branch, loop, and pause for a person's form before resuming days later. An AI copilot drafts tables, pages, and workflows from a plain-language prompt. The same views also become native Android and iOS apps with offline mode, PDF or image documents, and responsive emails. Every table, view, and page carries a minimum user role, and an auto-generated REST API exposes the data. Packs such as project management and an address book start an app from a ready template.

Any existing relational database becomes a collaborative, Airtable-style smart spreadsheet under NocoDB. It connects to PostgreSQL, MySQL, MariaDB, SQL Server, or SQLite, introspects the schema - tables, relationships, indexes - and renders it as interactive Grid, Gallery, Kanban, Calendar, and Form views without migrating a single row. Your business data stays in your database; NocoDB keeps only its own metadata (view configs, permissions, webhooks) in a separate store. Every connected table automatically gets REST APIs with Swagger documentation, effectively turning legacy databases into modern backends. The spreadsheet layer adds 20+ field types including formulas, lookups, rollups, links, attachments, and currency, plus sorting, filtering, grouping, and multi-field editing. Views can be locked or shared publicly with password protection, role-based access control scopes permissions per user, and webhooks plus CSV, Excel, and Airtable import round out integration. An ERD view visualizes the schema. Built with Node.js and Vue, deployed via Docker, handling millions of rows.

A budget model, the launch document that explains it, and the slides that present it can live side by side in one self-hosted office workspace that people and AI agents edit together. Personal and Team Spaces organize Sheets, Docs, Slides, relational Bases, and Boards, with Recent, Trash, file import, and export views keeping everyday housekeeping close at hand. Sharing follows role and node aware access control, including anonymous viewing, so a single table or document can be opened to a reader without exposing the whole space. Data and references stay connected across artifacts as the workspace changes, which keeps a figure corrected in a sheet consistent with the document that quotes it. The Workspace Agent drafts and revises content in isolated Worktrees, verifies its own changes, and hands the result to a person for review before anything reaches the trunk. Several review rounds can happen while humans keep editing in the Browser, and nothing merges until someone approves it. The Workspace CLI connects existing agents to your deployment, so automation can create content, inspect data, render screenshots and PDFs, and run layout checks before review. Sign-in accepts passwords, GitHub, Discord, or application OAuth, and files move in and out as XLSX, DOCX, PPTX, and CSV without a separate conversion project.

Koillection is a self-hosted physical collection and inventory manager that organizes books, vinyl records, video games, stamps, trading cards, and any custom hobby catalog using hierarchical folders, reusable metadata templates, wishlists, and loan tracking. Collectors can structure nested sub-collections like a file system and attach tailored attributes to each item, ranging from star ratings, purchase dates, and country flags to autographs, PDF manuals, and video clips. Reusable item templates and choice lists standardize data entry across uniform categories so adding a new comic issue or board game takes seconds rather than repetitive typing. Custom HTML and JSON scrapers let you pull item titles, cover art, and structured fields directly from external catalog websites into your forms using XPath or JMESPath selectors. Cross-collection tags link related pieces across separate folders, while dedicated photo albums store supplementary event galleries or condition photographs alongside your main inventory. Built-in wishlists track desired acquisitions with target prices and currencies, and a loan manager records which friend borrowed an item and when it was returned. Granular visibility settings let households run independent multi-user accounts or share read-only collection pages with guests, and a REST API exposes every catalog entity for external automation. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

With over 11,200 GitHub stars and adoption by France's sovereign digital workspace LaSuite serving 20,000+ government users, Grist is the relational spreadsheet that ends the false choice between fragile Excel files and expensive custom database development — storing all data in portable SQLite files while providing true relational structure where VLOOKUPs become actual linked records that update instantly across entire documents. Python-powered formulas replace complex Excel syntax with clear, readable logic using the full Python standard library, while familiar Excel functions remain available for users who prefer them. Granular access rules control permissions at row, column, table, and cell levels — not just entire sheets — enabling multi-department documents where each team sees only their authorized data. The flexible layout system combines spreadsheets, card views, charts, calendars, and custom widgets on configurable dashboard pages that transform raw data into operational interfaces. Real-time collaboration lets multiple users edit simultaneously with automatic snapshot history capturing every change for full audit trails and point-in-time recovery. AI formula assistance connects to OpenAI, Llama, or any OpenAI-compatible endpoint via OpenRouter to generate formulas from natural language descriptions. The REST API and webhooks enable integration with n8n, Zapier, and custom automation, while incremental imports keep external data sources synchronized. Deployable via Docker with OIDC, SAML, and SCIM authentication support. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache 2.0 licensed.

Every AI agent session starts from zero, and Busabase fixes that: it is an open-source workspace where agents and people share records, docs, skills, and apps, and every agent write arrives as a reviewable change. Bases hold typed records with relations, views, and forms, while Docs, Files, Whiteboards, and Workflows live in the same tree, so a project's data and context stay together. Skills are SKILL.md playbooks that any connected agent can look up before it acts. Each write becomes a Change Request carrying a message, a field-level diff, an author, and history; your permissions decide whether it merges at once or waits in the Inbox for approval, and any change can be reversed. Ask an agent to turn a Base into a dashboard, CRM, or content desk and it runs as an AirApp on live workspace data. Claude Code, Codex, Cursor, Gemini CLI, n8n, or your own process can connect through MCP, OpenAPI, the CLI, TypeScript and Python SDKs, or an in-app chat session. Templates install a complete setup, with sample data and an agent manual, in one command. Start it with one command and no accounts, because the open-source edition is a single-user workspace with no sign-in screen.

With over 15,000 GitHub stars and positioning itself as the most feature-complete open-source alternative to Airtable, APITable combines a buttery-smooth spreadsheet interface with a full database engine and automatic API generation that turns every datasheet into a queryable REST endpoint without writing a single line of backend code. Real-time collaborative editing powered by Operational Transformation algorithms supports 100,000+ rows with multiple simultaneous users, while seven built-in view types — Grid, Kanban, Gallery, Gantt chart, Calendar, Mindmap, and Form — let teams visualize the same data in whatever format suits their workflow. The one-click API panel exposes every table as a documented REST API with filtering, sorting, and pagination, effectively functioning as a backend-as-a-service for frontend developers and automation builders. Robot automation triggers workflows on record changes with integrations into n8n, Zapier, Appsmith, and Slack, while the extensible widget system provides 20+ open-source widgets for custom charts, dashboards, and data visualizations embedded directly into datasheets. Enterprise features include SAML single sign-on, field-level and row-level permissions via Mirrors, organizational team management, audit logging, database auto-backup, and data export. Bi-directional table linking with infinite cross-links creates relational data models across workspaces, and built-in templates cover CRM, project management, inventory, and content planning.

If you can write a SELECT statement, you can publish a working web app with SQLPage, where each query's results appear on the page as tables, charts, maps, or forms. A .sql file is a page. Name a component in the first row, and the rows after it become lists, cards, data grids, timelines, or step trackers. Tables offer searching, sorting, frozen headers, and per-row edit and delete buttons. Charts cover line, area, bar, pie, scatter, bubble, and heatmap views with a one-click CSV export. Forms feed INSERT and UPDATE statements directly, with validation and file uploads. A complete CRUD tool takes a handful of queries. The map component plots markers and GeoJSON shapes, and the JSON component lets the same data serve other systems as an API. Protect private pages with password logins or single sign-on through Google, Microsoft, or your own identity provider. Connect to SQLite, PostgreSQL, MySQL, SQL Server, or ODBC sources such as DuckDB, Oracle, Snowflake, and BigQuery. Tabs, modals, alerts, breadcrumbs, and carousels shape multi-page sites, and custom templates, CSS, and JavaScript fill any gap. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Datasette turns a database into an interactive website and JSON API, so anyone can browse, filter, and query the data without a custom backend. Point it at SQLite files and each table gets a page with sortable columns, per-column filters, full-text search where it is enabled, and facets that tally the values in a column, including array and date columns, with suggested facets surfaced automatically. Rows have their own URLs, foreign keys become links, and a row that other tables reference links to a filtered list of those records. A "View and edit SQL" link turns whatever filters you applied into an editable query, and visitors with permission can run read-only SQL with named parameters. Useful queries save as canned queries with their own URLs, and writable canned queries add forms that insert or update rows. Every page comes as JSON and as streaming CSV. A metadata file adds titles, licenses, sources, column descriptions, units, default sort orders, and hidden tables. Access rules can apply to the whole instance or a single database, table, or query. Plugins add charts, maps for latitude and longitude columns, Atom feeds, GitHub sign-in, and custom output formats. Custom templates, CSS, and static files carry your branding. SpatiaLite support adds geospatial queries, and datasette publish deploys to Google Cloud Run, Heroku, Vercel, or Fly.

Documents, tables, files, chat, and video meetings share one workspace in atomic.place, and AtomicServer is the part you host yourself so a team can edit together while the data stays on a machine it controls. Documents are collaborative rich text with comments, icons, and cover images, tables enforce a strict schema with keyboard navigation and copy and paste, and any table can switch to a kanban, calendar, dashboard, or timer view. Templates start an issue tracker, a CRM, a project task list, or a time tracker. Live cursors, typing indicators, and presence avatars show who is working where, group channels carry attachments, replies, and search, and an infinite canvas can be drawn on together. Every write is a signed commit, so a full history is kept. Read and write rights follow the resource hierarchy, and invite links bring people in. Websites are designed in the browser, published in one click, and rolled back to any earlier version. Custom classes and properties come from the Ontology Editor, small apps are plain JavaScript screens over the same data, and AI features work with any model through OpenRouter or a local Ollama and support MCP. Typeahead search suggests results as you type. A REST API answers in JSON-AD, Turtle, or JSON-LD for automation, and export and import commands write and read JSON-AD backups.
