We build simple, fast developer utilities that work in the browser — no installs, no accounts, no friction.
Every developer has been there — you need to quickly format some JSON, decode a JWT, test a regex, or generate a UUID, and suddenly you're opening a new tab, hunting for a tool that works, fighting ads, or being pushed to create an account just to paste some text.
CodeKitLab exists to fix that. Over 100 browser-based utilities — including ten AI-powered tools — all free, all instant, no sign-up required. We keep the tools fast, the UI clean, and the experience respectful of your time.
Tools load instantly. Everything runs in your browser. No waiting for servers to process simple transformations.
Your data stays in your browser. We never store inputs, log your tool usage, or sell data to third parties.
No accounts, no paywalls on core tools, no dark patterns. Open the tool, use it, close the tab.
AI tools add real value — explaining regex, fixing JSON, generating SQL — not just marketing fluff.
CodeKitLab is a product of Syscobyte AB, a Swedish software company building developer tools and monitoring infrastructure. We run lean, ship fast, and focus on products that solve real problems for engineers.
Our other product, AlertsDock, provides uptime monitoring and cron job health checks for APIs and scheduled tasks.
All tools are free. No account needed. Open a tool and get to work.
