4ga Boards
Instant board updates, side-by-side card multitasking, and a five-level task hierarchy make 4ga Boards a fast, clutter-free Kanban workspace for teams tired of sluggish project trackers. Work organizes cleanly from top-level projects down into boards, collapsible lists, cards, and granular subtask checklists. You can switch between classic drag-and-drop Kanban columns and compact to-do list views with a single click. While editing a card description in the rich Markdown editor with colored text, you can still scroll, filter, and rearrange other cards on the board without losing unsaved changes. Every move, label change, due date update, or comment syncs live across connected browsers without page reloads. Collapsible lists and a retractable sidebar free up wide-screen horizontal space during sprint reviews. Teams migrating existing workflows can import boards directly from Trello JSON exports or CSV files and export backups on demand. Cards support file attachments, custom cover images, multi-member assignments, and @mentions with instant activity notifications. Authentication integrates with Google, GitHub, Microsoft, and custom OIDC single sign-on providers alongside role-based board privacy. The interface includes dark mode, full keyboard shortcuts, and localization across 16 languages.

Claper
Passive slide decks put audiences to sleep, which is why Claper turns any presentation into a two-way live session where every attendee can vote in polls, submit questions, and react in real time from their phone. Speakers upload existing PDF or PowerPoint decks directly into the web studio and interleave interactive poll, quiz, form, and web embed slides between their static pages without rebuilding presentations from scratch. Conference organizers and educators share a short join code or QR link so hundreds of participants can enter the attendee room instantly from any mobile browser without installing an app or creating an account. During the talk, the presenter console displays incoming audience questions sorted by upvote popularity, alongside moderation controls to approve, pin, hide, or mark inquiries as answered on the main screen. Live polling supports multiple-choice, rating scale, and open-text prompts that animate into real-time bar charts and percentage breakdowns as votes arrive, while timed quizzes grade participant responses automatically. Integrated real-time speech transcription generates live captions and searchable session transcripts so international and hearing-impaired attendees can follow every spoken word. Universities and corporate training teams connect Claper directly to Moodle or OpenID Connect identity providers via LTI 1.3 to synchronize student rosters, push quiz scores to gradebooks, and export complete CSV engagement reports after every session.

salt.md
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.
OpenVidu
For online classes, telehealth visits, and support calls, OpenVidu Meet is a video meeting app that anyone with a link can join from a browser, with no account or download. A room needs only a name, and an optional wizard adds limits on participants (up to 30) and meeting length (up to a day), plus microphone and camera defaults. A shared Moderator or Speaker link admits anonymous guests, a personal link identifies each invited guest, and registered users sign in with their accounts. Developers can embed a room with an iframe or web component, and webhooks report meeting events to as many endpoints as needed. A smart mosaic favors recent speakers and counts the participants it hides, and a status rail shows the recording light, an encryption badge, and the time left. Moderators mute one participant's microphone, camera, or screen share, switch them off for everyone, remove people, and promote others. Virtual backgrounds blur the room or swap in an image, before joining or mid-call. Recordings start by hand or when the first participant, the second participant, or a moderator joins, in grid, speaker, or single-speaker layout. Permitted members can play, download, delete, or share saved recordings by link. End-to-end encryption protects audio, video, chat, and names behind a shared passphrase, though encrypted rooms cannot be recorded.
