About
About CallHeim.
On-call exists because production breaks and the right person has to be reached. CallHeim is built around one idea: that alert handling should be explainable, not just fast.
Why CallHeim exists
Production breaks at inconvenient times, and when it does, the right person has to be reached quickly — not eventually, and not the wrong person first. That is the whole job of an on-call tool, and most of them do it by making a decision on your behalf and not telling you why: a severity gets picked, alerts get grouped, and the reasoning stays inside the product.
CallHeim starts from the opposite assumption: that a team on call for production should be able to see why the tool did what it did. A suggested severity comes with the keywords that matched. A collapsed alert comes with the fingerprint and the window it collapsed inside. That is a narrower promise than “the platform decides everything for you”, and it is the one CallHeim is built to keep.
Philosophy
The principles the product is held to.
These are not values on a careers page. They are the rules the site and the product are both built against.
Explainable by default
Alert handling is rule-based and deterministic. Given the same alert, settings and state, CallHeim makes the same decision — and you can see why.
Private incident intelligence
No incident data is sent to any external LLM. Suggestions run as rule-based code in our own AWS account, and a person applies them.
Straightforward per-seat pricing
Published list prices per user per month, with what is tied to plan stated plainly rather than buried in a call.
Escalation you can reason about
Escalation runs on a state machine: an unanswered tier times out and advances to the next one, or the mandatory fallback, until someone acknowledges.
How it's built
On AWS, released through automated gates.
CallHeim runs on AWS, in the us-east-1 region.
Every tenant release runs automated tests, a type-check, lint, a secret scan and a dependency audit that blocks on critical findings before it deploys, and a failing step stops the deploy.
- Automated tests
- Type-check
- Lint
- Secret scan
- Dependency audit (blocks on critical findings)
- Deploy
A failing step stops the deploy; nothing ships around it.
