| Project | What it is | For |
|---|---|---|
| Toril | A desktop Markdown editor that renders as you type and keeps your notes as plain files. Works with Obsidian vaults. | Writers, staff and teams who keep notes and documents in plain Markdown |
| Tenajlo | A desktop Git client for self-hosted Forgejo, for people who'd rather not learn the command line. Git LFS built in. | Engineering and operations teams versioning code, PLC exports, CAD files and documents |
| Nu | A simple Python code editor for beginners, continuing the much-loved Mu editor. | Teachers, students and beginner programmers |
| TDS OpenAPI | A testable, machine-readable version of the TDS standard for booking trips across transit providers, with a conformance kit. | Transit agencies, demand-response and microtransit providers, and their vendors |
| Tag family | Small tools for plain semantic HTML that looks finished, behaves well, and is checked for mistakes. | Anyone writing web pages by hand or with an AI agent |
- TagBrush.css: classless CSS. One
<link>gives you layout, dark mode, forms and accessible colors. - TagAction: a tiny no-build script that adds sortable tables, copy buttons, dialogs and more. Pages still work with JavaScript off.
- TagCheck: finds semantic and accessibility mistakes in HTML, for people, CI and AI agents.
- TagKit: copy-paste page templates, plus themes for Jekyll, WordPress, Pandoc, MkDocs and Hugo.
Projects in progress or under evaluation:
- First Principles Code: a teaching template that shows engineers how to solve real problems in open-source Python.
- Sonome: reads a song's acoustic features and finds tracks with a similar sound, locally.
- Suggest. Anyone can post a need on the community forum. Upvotes and comments show how widely it's felt.
- Kovir decides. The kovir.org team chooses what Kovir Labs takes on, favoring needs that many organizations share.
- Labs builds and supports. Accepted ideas become open-source tools, maintained by Kovir Labs.
Kovir Labs is part of Kovir LLC, which helps under-resourced, mission-driven organizations grow through grant writing, organizational development and coaching.
