BYOK: zero markup on AI
Connect your Anthropic or OpenAI key in your profile and the agent bills your provider directly at standard rates. VibeKit doesn't see your tokens, doesn't add a margin, doesn't bundle credits you may not use. Prefer no key? Top up a USD balance and pay only for the sessions you actually run.

Add-ons

- Memory upgrade — bump an individual app's container to 512 MB or 1 GB.
- Extra custom domain — add domains beyond the plan's included count.
FAQ
Is VibeKit free to start?
Yes. The free tier includes 10 AI sessions per month, 1 hosted app, and 1 linked remote agent. No credit card required to sign up. Bring your own Anthropic or OpenAI key (BYOK) and you can run thousands of sessions without VibeKit ever charging you for AI usage.
What does BYOK mean and how does it work?
BYOK stands for Bring Your Own Key. You connect your Anthropic or OpenAI API key in your profile, and AI usage bills directly to that account at the provider's standard rates. VibeKit adds zero markup on BYOK usage — your subscription only covers the platform (hosting, persistent agents, infrastructure).
What's an AI session?
A session is one back-and-forth task with an agent — typically capped at 30 minutes of activity. Most simple tasks (a small feature, a bug fix, a deploy) finish in well under a session. Heavy refactors may use multiple sessions. The session counter resets on the 1st of each month.
Do unused sessions roll over?
No, sessions reset monthly. If you regularly hit your plan limit, an overage rate kicks in: $0.35/session on Builder, $0.25/session on Pro. The free tier doesn't have overage — it pauses until the next reset or until you upgrade.
Can I cancel anytime?
Yes. Cancel from your billing tab in the app — no email or support ticket required. Your account drops to the free tier on the next billing cycle. Hosted apps stay live; you just lose the higher session and app limits.
What if I run out of credit on the pay-as-you-go path?
Sessions pause until you top up. The agent doesn't run unauthorized usage. You can preset auto-top-up thresholds so the balance stays funded without manual attention.
Are there add-ons?
Yes — memory upgrades for individual apps (512MB / 1GB containers) and custom domains beyond plan limits. Add-ons stack with whatever plan you're on. Available from the Health drawer or your billing tab.
