Plans
| Plan | Price | Included |
|---|---|---|
| Starter | $0/month | 10,000 audit logs / month, 1,000 security detections / month |
| Pro | $20/month | 20,000 audit logs / month then $0.0001 per event, 10,000 security detections / month then $0.001 per event |
| Enterprise | Custom | Custom usage and retention |
The Starter plan at $0/month covers 10,000 audit logs / month, 1,000 security detections / month, which is where an agent would start. The top plan (Enterprise) is quoted rather than listed, so anything at that volume goes through a person.
Can an agent buy this on its own?
A price is only half the question. The other half is whether software can get from landing on the site to making a paid call without a person, which is what the AgentReady measures under adopt.
For Better Auth, it can create an account itself; billing is self-serve.
Against that, a sales call gates access; the signup flow assumes a human at a browser; credentials must be minted by hand in a dashboard. Each of those is a point where an unattended run stops and waits for a human.
That works out to 62/100 on adopt, against 57/100 overall.
What you are paying for
