Rystic builds local, stateful simulators of third-party APIs like Stripe, GitHub, and Kalshi that are validated against the real service and safe to reset
What it is
Rystic provides local, stateful simulators of the APIs that code and agents depend on. Each simulator is validated against the live service before release, with verification percentages published from CI per commit. The simulators run on your laptop or in CI with no rate limits, maintain state across calls, and allow you to seed any state before testing begins.
The platform includes simulators for Slack, GitHub, Kalshi, PayPal, Lob, Okta, Linear, Stripe, Resend, Anthropic, Clerk, Dropbox, Gmail, Google Drive, Jira, Notion, QuickBooks, S3, and Shopify, with more coming soon. Rystic enables testing without hitting live APIs, making it ideal for agent training, evaluation, and systems testing.
