Built for everyone.
Free forever.
Opekto is a growing library of free, browser-based utility tools. Every tool runs entirely in your browser — no login required, no installation, no account needed. You open it, and it works.
What we believe
Free means free
Every tool on Opekto is free and always will be. No paywalls, no premium tiers, no trials. Free tools for everyone, forever.
Your data is yours
Everything you type into any tool is processed locally in your browser. It never leaves your device. We have no access to it.
Built by the web
Every tool is suggested or built by a real person. Contributors are credited permanently and top contributors share in the revenue.
The toolkit
Currently 21 tools across 6 categories — Writing, Math, Developer, Health, Everyday, and Generator. New tools are added based on community suggestions.

Opekto is built on community contributions. When someone suggests a tool idea, their name is permanently credited on that tool's page and on our contributors hall of fame. Top contributors whose tools generate significant traffic may receive revenue sharing — we reach out directly.
