Frequently Asked Questions

Is the CLI really free forever?
Yes. Open source under MPL 2.0. No account, no trial period, no expiration. The free tier is not a marketing strategy that expires — it is the product.
What do I get with Post Pro?
Workflow Wizard for multi-step scenarios, field-level diff with HTML reports, AI-powered triage (BYOK), enhanced clinical datasets, and named vendor profiles. Everything the CLI does, plus the tools that make go-lives faster.
Can I try Pro before paying?
14-day free trial. No credit card required. You keep the free CLI regardless.
What is Founders Circle pricing?
The first 1,000 Founders Circle members get Post Pro at $14/mo locked for life (vs. $19/mo standard). Founders Circle members also get a 30-day trial (vs. 14-day), priority Loft beta access, and direct product team access.
