# FetchSandbox

> Your team ships code every day. How do you know it still works? FetchSandbox started with integrations. We’re extending verification to the rules teams depend on across services, jobs, data, and application code.

## Start here

- [Verification docs](https://fetchsandbox.com/docs): start with a change, define its rules, test the failures, inspect the evidence, and check the fix.
- [Guides](https://fetchsandbox.com/guides): rules, failure scenarios, evidence, and checking a fix.

## Available today

- [Free integration engine](https://fetchsandbox.com/install): connect through MCP and test supported integration workflows using controlled provider sandboxes.
- [MCP connection](https://fetchsandbox.com/mcp): local and hosted connection details for the available engine.
- [Engineering blog](https://fetchsandbox.com/blog): recorded examples and engineering explanations.

## Different use case?

We started with API-heavy teams. Teams changing background jobs, databases, services, and application code should contact us to agree the rules, environment, controls, and proof they need. This broader work is built with teams; current free MCP coverage is not a promise of universal software verification.

## Team pilots

- [Pilot process](https://fetchsandbox.com/#how-it-works): agree invariants, connect an isolated system, exercise agreed failure scenarios, and inspect a proof receipt.
- [Contact](mailto:hello@fetchsandbox.com): describe the system and what must never break. For broader jobs, databases, frontend, and connected systems, agree a team pilot scope and environment controls.

## Interpreting evidence

A pass applies only to the recorded version, observed scenario, assertions, and observation windows. A configured fault is not proof that the application experienced it. Failed checks and missing evidence must remain explicit. Illustrative website examples are not measured runs. A receipt is not blanket production-readiness approval. Deterministic verdict evaluation does not claim instruction-level replay of an independently hosted application.
