Free while we earn it
Everything self-serve is free — the tuner, the translator, and the public MCP server. Paying today is backing the project early, at an early price.
Written Agent Diagnostic — first 3 free, then $99
One written decision memo for one deployed agent: the five-primitive profile, failure-risk score, recommended runtime posture, and the next test to run — delivered to your inbox. Staged the same way we publish claims: the first three case-study seats are free in exchange for an anonymized public case study — you get the memo, we earn the receipts. Once those case studies are published, the next seats pay the $99 founding rate with the evidence in front of them. No one is asked to pay for an unproven service.

Frequently asked questions
What do I get with the free tier?
The whole self-serve product: the tuner at /tuner, the Translator Hub at /translator, and the public MCP server. No API key, no account.
How does the founding diagnostic work?
Two stages. Stage 1: the first three seats are free — submit a brief about one agent or workflow, get the full written memo (primitives, risk score, posture, next tests), and agree to an anonymized public case study. Stage 2: once those case studies are published, the next seats pay the $99 founding rate, with the receipts visible before you buy. You can also skip the free queue at any time by paying $99 with no case-study obligation.
What is the Founding supporter tier?
Early-supporter pricing: $9/month or $79/year, versus $40/month at v1. The rate locks for as long as your subscription stays active. Includes the SDK license key.
Does the SDK send data to your servers?
No. The recommend() and translator functions are pure local computation. License key validation is a local JWT check. Nothing is sent to rpcs1.dev at call time.
Can I upgrade or downgrade?
Yes. Upgrade anytime. Downgrades take effect at the end of the current billing period.
What payment methods do you accept?
All major credit cards via Stripe. Promotion codes are supported at checkout.
