Deltatime is a free coding time tracker that helps you see how much time you spend programming. It tracks your coding time across different languages and editors.

Yes! Deltatime is completely free to use. There are no paid plans or hidden costs.

How is Deltatime different from WakaTime?

Deltatime is free and open source, while WakaTime has paid plans. Deltatime gives you all features for free and you can host it yourself.

Is Deltatime the same as WakaTime?

No. Deltatime is a separate, independent open-source project. While both track coding time, Deltatime is completely free and its community lives on Discord rather than WakaTime's paid platform.

Your coding data should belong to you

We have an extensive API you can play around with, and you can export your data to any tool you like, anytime.

Built by the makers at Hack Club. Anyone can contribute to the codebase and help shape the product!

Everything you need, nothing you don't.

Granular telemetry for your development environment that helps you stay productive.

Time tracking

Automatic tracking that starts when you type and stops when you take a break.

Language stats

See your actual tech stack - how much time do you spend writing React vs Svelte?

File-level insights

Drill into specific files and find the ones consuming all your time.

Zero lock-in

Your data is yours. Export your entire history as JSON.

Leaderboards (coming soon)

Create private leaderboards for your team or hackathon.

Privacy-first

Works where you work.

Deltatime uses the open-source WakaTime plugin ecosystem. If your editor has a plugin, it works with Deltatime.

Frequently Asked Questions

Is this really free?

Yep. Deltatime is a free service by Hack Club. We made it for ourselves and our events, and it's good marketing :)

Is my code private?

Can I self-host this?
