Every developer has done it — copy-pasted a JWT, a private key, or a JSON blob with sensitive data into some random website and held their breath. Wondering if it was being logged, tracked, or worse. Every developer has done it — copy-pasted a JWT, a private key, or a JSON blob with sensitive data into some random website and held their breath. Wondering if it was being logged, tracked, or worse. I built KRUMB.DEV because I wanted tools that didn't make me feel dirty after using them. What Is It? 46 developer tools, all in one place. No signup. No uploads. No tracking. Open source. The terminal-inspired interface isn't just aesthetic — it's a constraint. Every tool fits in a single column, zero sidebar, zero popups. Just you and the tool. What's Inside Formatters — JSON, SQL (17 dialects), HTML, JavaScript, CSS Encoders — Base64, URL, JWT decoder, YAML↔JSON, JSON↔CSV Generators — Passwords, UUIDs (v1/v3/v4/v5), hashes (MD5/SHA/HMAC), QR codes, Lorem Ipsum, color palettes, CSS gradients/shadows/grids, meta tags, robots.txt, .gitignore Testing & Debugging — Regex tester, diff checker, webhook tester, cURL→code, HTTP status reference, cron expression builder Converters — Unix timestamps, hex↔RGB, binary, SVG→JSX, JSON→TypeScript, HTML playground, markdown editor Network — DNS lookup, SSL checker, IP lookup, QR code decoder, IBAN validator Why I Built It This Way Most "free" dev tools follow the same pattern: create an account, hit a rate limit, and wonder if your data is being stored somewhere. KRUMB.DEV flips that: Everything runs in your browser — JSON, JWT, source code, passwords never touch a network request Zero accounts — open the page, use the tool, leave. No signup wall between you and the output Clean interface — ⌘K opens a command palette to jump to any tool in seconds Open source — MIT license, deploy your own if you want The Tech Next.js, TypeScript, and Tailwind. Static-first, client-side execution for all core tools. Server routes exist only for DNS/SSL l

I built a small API gateway for Chinese AI models (DeepSeek, etc.) and decided to audit my own token usage. Nothing fancy — just 78 test requests. What I found: 76 successful calls → 13,103 tokens total (avg ~172 per call) 2 calls failed → invalid model name (no cost, but indicates misconfiguration) Worst case: 1,086 input tokens → 2 output tokens. Yes, someone pasted a massive document and got a 2-token reply. This is like using a Ferrari to deliver a pizza. If this happens at enterprise scale, the waste is astronomical. Companies are throwing money at AI APIs without knowing where it's going. What I'm building: A Token Audit tool that catches: ❌ Duplicate content submissions ❌ Expensive models used for trivial queries ❌ Nighttime spikes (potential key leaks) Would you use this for your team? Any feedback is appreciated. P.S. This is my own test data, not customer data. Just validating the problem.

Descript costs $24/mo, so I built this over a single weekend with Fable! Introducing Rescript: edit videos by simply editing the transcript text. Drop in a video and it is transcribed locally with per-word timestamps and speaker labels. Delete words in the transcript and the corresponding clip is cut from the video. Runs fully in the browser: Local, free, offline and open source. → Github https://github.com/wassgha/rescript → App https://wassgha.github.io/rescript

TanStack Table V9 is a beta release of a headless UI library for creating tables in various JavaScript frameworks. It features improved state management, memory usage, and extensibility. The notable change is an opt-in feature model, allowing developers to load only necessary components. Migration is gradual, with tools provided for legacy support. The library remains free and developer-focused. By Daniel Curtis

As a software dev, I really enjoy having live coding videos playing in the background while I work. But it's surprisingly difficult to find hour+ long videos of coding without commentary on Youtube. What I really wanted was an infinite coding video, so I built one. Pick your IDE/monitor/ambience of choice, hit the Screensaver button, put it on a second monitor or TV, and enjoy infinite coding ASMR.
