Frequently asked questions
Is it really free? What's the catch?
There is no catch. Zest is open source under the MIT license. Commercial sites, personal projects, agency work — it all works. No per-site fees, no pageview caps. Self-host it and it is yours.
Can I use Zest on client websites?
Yes. The MIT license covers unlimited client sites at no cost.
Do I need to credit Zest or show your branding?
No. Theme it however you want. White-label it. The banner is yours.
What's the Enterprise plan?
Enterprise is for teams that need more than the self-serve setup. Custom integrations, compliance audits, someone to walk you through onboarding. It is a service, not a license key. If that fits, reach out.
