Built by Developers,
For Developers
DevPlaybook is a free hub of 40+ essential developer tools — no login required, no ads, no friction. Just fast, reliable tools you can use right now.
Our Mission
Developer tools should be fast, free, and frictionless. Too many useful tools are buried behind paywalls, cluttered with ads, or require creating an account just to convert a timestamp.
We built DevPlaybook to fix that. Every tool on this site runs entirely in your browser — no data sent to servers, no sign-up required, no waiting. Open the page, use the tool, done.
Beyond tools, we curate the best resources, workflows, and references to help developers ship faster and learn smarter.

What Developers Say
DevPlaybook is my go-to for quick dev tools. JSON formatter alone saves me 10 minutes a day.
Finally a site where I can format JSON, convert timestamps, and check regex — all without signing up or dealing with ads.
The curated tool list is genuinely useful. Not bloated with affiliate spam — just real tools developers actually use.
Open & Transparent
DevPlaybook is built in public. We share our stack, our tools list, and our roadmap openly. No black boxes, no dark patterns.
If you find a bug, have a tool request, or want to contribute a resource — reach out. We read every message.
