A browser extension that captures console errors, failed network requests, and a session replay into one shareable link so users can report bugs without typing a description.
A self-hosted tool that periodically restores random files and databases from your backups into a scratch environment to prove they actually work, not just that they exist.
A CLI that diffs OpenAPI specs between commits or environments and fails the build on breaking changes, catching contract drift before it ships.
A CLI that reads commits and merged PRs since your last tag, groups them by type, and drafts a changelog and release notes post for you to edit and ship.
A self-hosted proxy that sits in front of your webhook endpoints, logs every payload verbatim, and lets you replay or edit-and-replay failed deliveries on demand.
A Tauri app that reads your project directories, lists all .env files, and lets you view, edit, and compare environment variables without touching a terminal.
A YAML-configured single-page app that lists all your team's internal services with live status badges — a shared browser start page with no database and no account required.
A single-binary local reverse proxy that enforces configurable rate limits on outbound API requests, preventing 429s from third-party services without changing a line of application code.
An n8n workflow that catches GitHub PR webhooks, sends each diff to a local Ollama model, and posts a review comment back — no external AI API required.
A CLI tool that hits a real HTTP endpoint, captures the response shape, and writes a TypeScript interface and optional Zod schema — no manual JSON pasting required.
A browser extension that records user clicks and form interactions, then exports them as ready-to-run Playwright test scripts — no manual test authoring needed.
A CLI tool that diffs two OpenAPI specs, classifies each change as breaking or safe, and exits non-zero in CI so you catch accidental contract regressions before they ship.
A terminal UI app that lets developers open any SQLite file, browse tables and schemas, and run arbitrary SQL queries — all without leaving the command line or installing a GUI.
A lightweight self-hosted service that captures, stores, and replays inbound HTTP webhooks so developers can debug third-party integrations without exposing localhost or paying for managed tunnels.
