Trusted by Mistral AI, PayPal, Groq, and Synthesia with over 10,300 GitHub stars and Y Combinator backing, Lago is the open-source billing engine that handles usage-based, subscription-based, and hybrid pricing models through a single API-first platform — replacing the need to build custom billing logic or depend on opaque SaaS pricing infrastructure. Real-time event ingestion via ClickHouse processes billable events with deduplication and multiple aggregation methods including count, sum, unique count, max, and weighted sum, while graduated pricing tiers, package-based billing, and percentage-based fees model any pricing strategy from simple subscriptions to complex marketplace commission structures. Automated invoice generation calculates charges according to configurable billing cycles with grace periods, proration for mid-cycle changes, and credit note issuance for refunds and adjustments. Prepaid credits enable pay-in-advance models where customers purchase credit blocks and draw down as usage accumulates, while entitlements tie feature access directly to billing plans for automated provisioning and de-provisioning. Payment orchestration integrates natively with Stripe, Adyen, and GoCardless with automatic retry logic, dunning workflows for failed payments, and multi-gateway routing. Revenue analytics provide cross-stream visibility into MRR, usage trends, churn, and revenue drivers through dedicated API endpoints. The customer portal embeds into your application for self-service invoice access and usage monitoring. 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.

Images, text, audio, video, HTML, PDFs, and time series, labeled in one tool with a standardized output format: Label Studio is the open-source data labeling platform for building training datasets. Computer vision tasks cover classification, object detection (boxes, polygons, ellipses, keypoints), and semantic segmentation; audio work spans transcription, speaker diarization, and emotion recognition; NLP handles named entity recognition and document classification with taxonomies up to 10,000 classes; and GenAI workflows support LLM fine-tuning data and RLHF response ranking. Labeling interfaces are fully configurable with an XML-like templating language, so the UI matches the task instead of the reverse. The ML backend SDK turns any model into a connected web server for pre-annotation (model predicts, humans verify), interactive labeling (real-time predictions as annotators draw regions or highlight text), and model evaluation - cutting annotation time dramatically on large datasets. Data imports from S3, GCS, or file uploads; the Data Manager filters and explores tasks; exports convert to the format your ML library expects via label-studio-converter. Multi-user accounts tie every annotation to its author, and webhooks, a Python SDK, and REST API embed labeling into any pipeline. Self-hosting keeps proprietary training data - often a company's most sensitive asset - entirely on your infrastructure.

An entire backend in a single Go executable: PocketBase embeds SQLite with realtime subscriptions, authentication and user management, file storage, and an admin dashboard, all behind a REST-ish API. SQLite runs in WAL mode, which outperforms client-server databases for the read-heavy workloads typical of small and mid-sized apps. Authentication supports email/password, one-time passwords, and 15+ OAuth2 providers including Google, Apple, and GitHub, with stateless tokens. Clients subscribe to record changes over server-sent events, and official JavaScript and Dart SDKs cover web, mobile, and Flutter frontends. Collections, rules, and API access permissions are managed visually in the admin UI. When you need custom logic, extend it with JavaScript hooks running in the embedded JS VM of the prebuilt binary, or import PocketBase as a Go library and compile custom business logic into your own single-file backend. File storage attaches uploads to records with thumbnail generation for images and optional S3-compatible external storage. All state lives in one pb_data directory, so backup is a directory copy and upgrade is replacing a binary - one of the lowest-maintenance backends you can run. The contrast with Firebase is the point: where usage-based pricing scales with reads, writes, and bandwidth, PocketBase runs the entire backend at flat hosting cost, and the data is a plain SQLite file you can copy anywhere.

Backed by 12,400+ GitHub stars and positioned as the self-hosted alternative to FullStory and Hotjar, OpenReplay delivers the open-source session replay platform that keeps every byte of user behavior data on your own infrastructure. The JavaScript tracker captures pixel-perfect recordings of clicks, scrolls, form inputs, and navigation with automatic sensitive data masking, while simultaneously logging network requests, console errors, JavaScript exceptions, and Redux, VueX, MobX, NgRx, Pinia, and Zustand store state changes for complete technical context. DevTools mode reconstructs each session with full stack traces, GraphQL queries from Apollo and Relay, Fetch and Axios request payloads, CPU and memory metrics, and page speed waterfall charts — effectively giving developers a browser inspector tied to any user session. Product analytics surfaces conversion funnels, user journeys, click heatmaps, web vitals trends, and retention cohorts without requiring custom instrumentation. Co-browsing connects support agents to live user sessions with cursor control and WebRTC audio, enabling real-time assistance without third-party screen-sharing software. Integrations push session context into Sentry, Datadog, CloudWatch, Stackdriver, and Elastic for front-to-back debugging. Feature flags enable gradual rollouts with session-level targeting. The platform deploys to any cloud via Docker and Kubernetes with auto-scaling ingestion handling up to 50,000 sessions per month on the open-source edition.

KrakenD processes over 18,000 requests per second on a single instance while consuming under 50MB of RAM at 1,000 concurrent connections, operating as a stateless API gateway that requires no database whatsoever. The Community Edition has earned over 2,600 GitHub stars by outperforming database-dependent alternatives like Kong and Tyk in independent benchmarks. Written entirely in Go, it uses declarative JSON or YAML configuration files that integrate directly into GitOps workflows for version-controlled infrastructure management. The gateway aggregates responses from multiple backend services into a single API call, transforms request and response payloads with field filtering, grouping, and mapping, and applies zero-trust security policies including JWT validation, OAuth 2.0, CORS, HSTS, clickjacking protection, and XSS prevention. Traffic management features include multi-layer rate limiting at both the router and proxy levels, circuit breakers for backend fault isolation, spike arrest policies, and concurrent call support that requests the same data from multiple backends in parallel for improved response times. Telemetry integrates with OpenTelemetry, Prometheus, Grafana dashboards, Datadog, Zipkin, and Jaeger for distributed tracing and metrics collection. The gateway extends through Go plugins, Lua scripting, Martian modifiers, and Google CEL expressions for custom request processing logic. AI workload routing supports OpenAI, Anthropic, Gemini, and other model endpoints with built-in fallback, retries, and load balancing.

Terminals, remote desktops, and file browsers for every server you run: Nexterm opens them over SSH, VNC, RDP, Telnet, or SFTP from a self-hosted web page. Servers live in folders with tags and custom icons. Connections open as tabs or split views, keep running across browsers and devices, and can hibernate and resume later. The file manager handles SFTP and FTP: drag files in, upload whole folders, search, and edit in place with syntax highlighting. Live metrics track CPU, memory, disk, network, and processes for each host. Snippets store the commands you retype most. Scripts run whole maintenance jobs. Git repositories added as sources bring ready-made ones filtered by operating system. Organizations share servers through role-based permissions, and every action is logged. Record full terminal sessions for audits and training, or send a shared-session link so a colleague can join, read-only or writable. Authentication covers local accounts with TOTP and passkeys, OIDC providers such as Keycloak, Authentik, and Microsoft Entra ID, and LDAP or Active Directory. Saved passwords, SSH keys, and passphrases stay encrypted at rest. A Proxmox integration lists LXC containers and QEMU virtual machines and can start or stop them. An opt-in AI assistant drafts shell commands from plain-language requests.

Archiving online videos, creator channels, and curated playlists directly into a personal Plex, Jellyfin, or Emby library becomes effortless with HomeTube, a self-hosted web downloader supporting more than 1,800 streaming platforms. Users paste a single video or playlist URL into the web interface, where an intelligent format analyzer evaluates available codecs and automatically selects the highest resolution video and audio streams such as 4K AV1 or VP9 paired with Opus audio. Built-in SponsorBlock integration detects crowd-sourced sponsor segments, intros, outros, and self-promotions during the download process so saved videos play back completely ad-free without manual editing. When synchronizing playlists, the engine tracks entries by unique video ID rather than mutable titles, downloads only newly added items, preserves upstream ordering with customizable filename templates, and optionally moves removed videos into an archive folder. A visual processing panel lets operators trim specific time ranges with keyframe or frame-precise cutting, embed primary and secondary subtitle tracks alongside chapter markers, and create nested destination directories directly from the browser. Browser cookie file support unlocks age-restricted or member-only streams, while custom yt-dlp argument pass-through accommodates proxy routing and filesize caps. Once processing finishes, completed files move into watched media folders and can trigger an immediate Jellyfin library rescan via API key.

Webstudio delivers a professional-grade visual website builder that outputs semantic HTML and clean CSS without inline style pollution or JavaScript-heavy render paths. The live canvas editor provides direct manipulation of all CSS properties — flexbox, grid, spacing, typography, transforms, and filters — with real-time preview across responsive breakpoints. The component system supports reusable instances with variants and overrides, while design tokens maintain consistent colors, fonts, and spacing across the entire site. Data bindings connect to external content sources through native integrations with Strapi and Supabase, plus a generic CMS interface for any REST API backend. The Scroll Timeline API powers animations at 120 FPS off the main thread, with presets for rotate, scale, translate, opacity, color, and filter effects. Projects build as dynamic Remix applications with server-side rendering or export as static HTML, CSS, and JavaScript files. The Webstudio CLI generates Docker-ready builds that run a Node.js server on port 3000, with Nginx reverse proxy configuration for SSL termination via Let's Encrypt. The builder requires minimum 1 GB RAM and 1 CPU core for Docker builds. MCP integration enables AI agents to create and modify websites programmatically. On RepoCloud, deploy Webstudio projects on a dedicated VPS with root SSH access, persistent storage, and complete control over your hosting, custom domains, and deployment pipeline, all under the AGPL-3.0 license.

To protect self-hosted web services behind a unified single sign-on portal without deploying complex enterprise identity suites, Tinyauth acts as an OpenID Certified authentication server and reverse proxy middleware. Homelab operators and infrastructure teams place it in front of internal dashboards, media servers, and administrative tools routed through Traefik, Caddy, Nginx, Nginx Proxy Manager, or LinuxServer SWAG. Users can sign in with local bcrypt-hashed credentials, scan QR codes to enroll time-based one-time password authenticators for two-factor verification, or authenticate through external OAuth providers like GitHub, Google, and Pocket ID. Organizations running centralized directories can bind Tinyauth directly to an LDAP server such as LLDAP or OpenLDAP and automatically synchronize group memberships for role-based authorization. Fine-grained access control rules configured via dynamic Docker container labels or environment variables let administrators whitelist or block specific usernames, OAuth email regex patterns, OIDC groups, client IP CIDR ranges, and URL path prefixes per subdomain. For applications that support native federated login, the built-in OpenID Connect 1.0 discovery endpoint, authorization code flow, and userinfo API allow seamless single sign-on with optional consent skipping for trusted clients.

Sharry moves files in both directions: you hand someone a download link, and they hand files back to you, without either side juggling accounts on a commercial transfer service. Upload a file and you get a public URL that is hard to guess but open to anyone who has it; add a password as a second secret, set how long the share lives, and cap how many times it may be downloaded. Expired shares clean themselves up on a schedule. Uploads run over the tus protocol, so a dropped connection in the middle of a two-gigabyte video is an inconvenience, not a restart: send the same file again and it resumes from the last received chunk. Downloads support caching and range requests, which means recipients can stream a video in the browser and scrub its timeline instead of waiting for the whole file. The reverse direction is what makes Sharry unusual: every registered user can maintain alias pages behind their own unguessable URLs, where clients, students, or family members upload files straight to that user, with an email notification when something arrives. Everything is scriptable through a documented REST API, and files can live in the database, on the filesystem, or in S3-compatible storage.

Report cards, attendance rosters, class schedules, discipline logs, and fee statements all live in one browser-based system with RosarioSIS, an open-source student information system for K-12 schools and similar institutions. Administrators define marking periods in up to three tiers, set grade levels and daily periods, and search students by gender, grade level, schedule, absences, GPA, or class rank. The scheduler places whole classes or a single student, and runs in test mode each time a student's requests are saved, so conflicts can be resolved with the student still in front of you. Teachers keep a weighted gradebook with grade ranges, progress reports, report cards, and transcripts, take attendance electronically, and use the eligibility feature to flag who may join athletic or academic activities. Discipline logs, student billing with fees, payments, balances, and statements, food service, and accounting complete the core modules. Parents and students get their own portal, new families can register online, listings export to Excel, CSV, or XML, and charts and PDF documents support decisions and paperwork. The interface adapts to tablets and phones and is translated into a dozen languages. Add-on modules bring email, library, hostel, Jitsi Meet video rooms, and Moodle integration.

Follow every blog, newsletter, and news site you like from one distraction-free inbox with the self-hosted Fusion RSS reader, which has no AI features by design. A left sidebar lists feed groups with unread counts and jumps between Unread, Starred, and All, while the center list shows articles under filter tabs with read and star buttons on every card. Click a card and a right-hand drawer opens with the full sanitized article, a link to the original, and Previous and Next buttons. Press Cmd or Ctrl+K, or the slash key, to search feeds and articles from anywhere. Stay on the keyboard with Google Reader-style keys such as j and k to move, m to mark read, s to star, and g then u to jump to Unread; the question mark lists them all. Add a feed by entering a site address and letting auto-discovery find it, then pick its group, refresh frequency, and HTTP proxy, or suspend it to pause updates. OPML import and export bring subscriptions in or out. Starred articles are saved as snapshots that outlive their source feed. Fever API compatibility lets Reeder, Unread, and FeedMe read the same library. Sign in with a password or OIDC single sign-on, and install the interface as a PWA with Light, Dark, and System themes in eight languages.
