Extension Runtime.
Add your own code without forking the platform
When your product needs something truly custom, your own services run alongside the platform in the same AWS account, rather than in a forked copy you have to maintain. Each release is health-checked as it goes out and rolled back automatically if it fails.
For your engineers.
What is included, in the terms your technical team will ask about.
Three process kinds: webhook consumers, HTTP services, static frontends
Deploy saga with digest pinning, health gating, and compensation
A dedicated IAM role per extension, not a shared cluster identity
Signed webhooks with overlapping secret rotation
Scale-to-zero on queue depth; blue/green rollouts for HTTP services
Starter templates for TypeScript, Python, and Scala
Works with everything.
Extension Runtime integrates seamlessly with other Functory capabilities and your existing tools.
