delphitools (GitHub)

MIT source for the delphi.tools utility collection, self-hostable via Docker

Tier B · UsefulToolGeneratorgithub.com

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.

Install

docker build -t delphitools:latest . && docker run --rm -p 3000:80 delphitools:latest

For an agent

Use 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.
