Show HN: Rystic – Stateful Local Simulators of Slack, GitHub and Linear
Hi HN, we're Zach and Evan, founders of Rystic ( https://www.rystic.ai ). As LLMs have progressed, producing code has become fast and cheap but verification has not. At my previous company I noticed that whenever I could test a service locally or in CI this bottleneck went away. If a service needed to use a shared sandbox or staging environment to run integration tests, verification was a huge pain. At Rystic we are taking that idea and applying it to every third-party service. We are trying to

Who is affected
Identify the existing workflow this change affects before recommending an upgrade. Launch attention does not establish improvement; an API, pricing or availability change may instead create migration work.
Missing comparison points
Missing checks: old versus new behavior, affected plans and regions, availability date, compatibility, rollback path and cost under the same workload.
Migration check
Save the release or policy notice, run the same task on the old and new option, and compare outputs and the full bill. For retirement notices, verify the deadline before scheduling migration.
