delphitools (GitHub)
MIT source for the delphi.tools utility collection, self-hostable via Docker
The source for delphi.tools, described by its author as 'a collection of small, low stakes and low effort tools. No logins, no registration, no data collection.' It is a Next.js + TypeScript + Tailwind + shadcn/ui app with each of its ~56 utilities as a self-contained component under `components/tools/`, served through one dynamic `/tools/[toolId]` route. A Dockerfile and compose file make it a two-command self-host, and the repo carries SPEC.md, PARITY.md and BUILD-PLAN.md documenting how tools are specified and kept consistent. MIT-licensed, ~719 stars, actively pushed.
docker build -t delphitools:latest . && docker run --rm -p 3000:80 delphitools:latestUse the repo, not the site, when you need the logic rather than the result: every utility is one file under `components/tools/` (for example `tailwind-shades.tsx`, `image-tracer.tsx`, `pdf-preflight.tsx`), MIT-licensed and dependency-light, so it copies cleanly into another Next.js app. It is also a decent worked example of a shadcn/ui app with dozens of routes behind a single dynamic segment plus per-tool OG image generation. Self-host with the Docker commands if a team wants these utilities without sending images to a third-party site.
Why it is here. A rare case where an ad-free public utility site publishes its whole implementation under MIT — the tool code is as reusable as the tools themselves.
- MIT source for ~56 utilities
- one file per tool, easy to lift
- Docker self-host in two commands
- Next.js + shadcn/ui reference app
- SPEC.md and PARITY.md document the tool contract
