Salesforce is the only part of your stack with no real CI.
Every deploy is "tested" but the failures that make the pager go off have never run once: the row lock, the rate limit, the retry that double-charges. You can't rehearse them in any sandbox, at any price.
Fidelic is a Salesforce org you can boot, break, and throw away.
A 17.6MB Docker container that loads your real schema and runs your real Apex triggers. Point your tests at localhost with same REST responses, same trigger side effects, same validation errors. Then flip a switch and get the failures no real org allows: row locks, rate limits, latency, on command. Wiped clean between tests. As many in parallel as your CI has cores.

Every trigger is classified at boot: executed, simulated, recorded-only, or refused with a reason.
Or run it now, in your browser.
play.fidelic.dev hands you a real NPSP org — the actual open-source nonprofit codebase, 26 triggers, 7 of them executing real Apex. Click a command, watch the triggers fire, throw the org away. No install, no signup, no Salesforce login.

A handful of sandboxes run at a time. If they are all busy you will be given the command to run it yourself instead.
Verified 66/66 against the public conformance suite run the scorecard yourself →
66/66 pass · 5 skipped (need a real org) · 2 pending (awaiting real-org verification). The skips and pendings are the methodology showing its work.
The failure injection alone is worth it. Row locks and API limits are untestable in any real org. Fidelic makes them a config flag.
