Pricing
Free while we are building. Free for you after that.
Everything on Zenzei is free during early access. When paid tiers arrive, individual and community use stays free — that split was decided before there was anything to sell.

Questions
- Is the free tier a trial?
- No. Individual and community use is free permanently. We committed to that early, before having anything to sell, specifically so there could never be a bait-and-switch later.
- Then what would you eventually charge for?
- Team and commercial use — CI runs, seats, verification IP, priority capacity. Things a company needs and an individual learner does not.
- Why is it free right now?
- Two reasons, both honest. The platform is early and still proving itself. And every run is real-world testing that hardens our own simulator — free usage is genuinely valuable to us.
- Do I need an account?
- Yes, to run code. Your submissions execute on our infrastructure, and running untrusted code for anonymous traffic is not something we are willing to do. Browsing the site needs nothing.
- What happens to my code?
- It stays yours. We store it so you can revisit your own history, and run it to return results. Row-level security means other users cannot read it. See the privacy policy.
