Heap vs Mixpanel for AI agents
As of 12 Oct 2026, Mixpanel gets an AI agent further: L3 · Does the work against L1 · Needs a person.
- Find: Some docs for agents: llms.txt and an OpenAPI.
- Access: Can't sign up.
- Use: Work not reached.
- Pay: Payment not reached.
- Leave: Leaving not reached.
Stopped at sign up: needs a human. Next: let an agent sign up on its own
Needs a person to get in: L1 · Needs a person. Our agent read Heap's docs, which already suit an agent well: an llms.txt, Markdown pages, and an OpenAPI definition on every reference page. Sign-up only runs through a web form, and submitting it showed a reCAPTCHA image puzzle our agent couldn't get past. No account was made, so verifying, getting a key and calling the API were never reached. Paying wasn't tested either: checkout sits behind the same sign-up, and Heap's Growth pricing asks a person to sign up for an estimate. With no account, there was nothing to cancel or delete.

Gets in on its own: L3 · Does the work. Sign-up is a browser form with no CAPTCHA, but the first credential, a service account, only exists in the web UI, and so does the key for the project token. From there our agent ran ingestion, raw export, feature flags, experiments, Lexicon and boards headless through the official MCP server, with each task read back. Every analysis query returned a payment-required response on the free plan, and upgrading asked for a card in a checkout form. Deleting the organization is a web button, and the confirmation mail says data clears after a wait, so our agent could not confirm the account was gone before the drive ended.
