Question 1

What is Runmark and what problem does it solve?

Accepted Answer

Runmark is a local-first development environment observability, fingerprinting, comparison, and verification tool designed to permanently eliminate 'works on my machine' issues across teams and CI pipelines.

Question 2

How does Runmark detect development environment drift?

Accepted Answer

Runmark scans runtime interpreters, package dependencies, OS packages, port bindings, and environment variables into a deterministic canonical digest and compares it against expected environment contracts.

Question 3

How does Runmark compare to Docker?

Accepted Answer

Runmark works directly on native host environments without the heavy overhead, virtualization, or build times of Docker containers, while also being able to verify inside containers and CI jobs.

Question 4

Does Runmark inspect or leak sensitive secrets?

Accepted Answer

No. Runmark features a zero-secret security architecture. Environment variable values matching secret heuristics (API tokens, passwords, private keys) are automatically redacted locally before calculating digests.

Question 5

How do I install Runmark?

Accepted Answer

Runmark is available on PyPI. You can install it using 'pip install runmark' or run it directly in your virtual environment.
