How we build
Production-grade.
Not Zapier in a trench coat.
Every Rex integration we ship handles failure properly: idempotent jobs, retry logic, dead-letter queues for unrecoverable cases, and observability so you can see exactly where data is at any moment.
Tested
Real test suite, real edge cases. Not just "it worked once."
Observable
You see what is happening — events logged, errors surfaced.
Maintainable
Documented, version-controlled, handed over properly.

FAQ
Common questions about Rex integration.
Can you build custom integrations with Rex?
Yes — Rex has a public API supporting the integration patterns we typically build, including custom websites, buyer portals, and lead capture flows.
How does Rex compare to AgentBox?
Rex tends to win on workflow automation depth; AgentBox has tighter Domain integration. Both work well for sales agencies; the right choice is usually whichever fits your existing team and process.
Can Rex handle multi-office agencies?
Yes — Rex supports multi-office configurations natively, and we build agency-wide platforms on top with consistent brand across locations.
