Questions & Answers

As answered by people managing kdiff3 and Jaah.

How would you describe the primary audience of your product?

Jaah's answer:

Engineering leaders, teams and solo developers who want to hand real work to AI agents without lowering the bar for what reaches production: teams that care about review, security, governance and keeping code on their own infrastructure.

What makes your product unique?

Jaah's answer:

Jaah doesn't just generate code; it gets code to production. Every task runs through a staged pipeline and comes back as a pull request that has passed your own tests plus code, security and acceptance review, corporate guardrails, with a report showing the evidence for each acceptance criterion, everything is auditable.

Why should a person choose your product over its competitors?

Jaah's answer:

Coding agents are cheap; trusting their output is the hard part. Jaah carries your standards into every repository, enforces branch protection agents cannot bypass, and keeps every action on record.

What's the story behind your product?

Jaah's answer:

Jaah (Just Another Agentic Harness) was built by its own agents, running in its own harness, on tasks its own pipeline handed them, and it still is. Every change to the product is worked by the same pipeline it sells, under the same reviews, and merged the same way. But at its origin it was devised by a team who started to be cognitively overloaded by all the AI agents it was running.

Which are the primary technologies used for building your product?

Jaah's answer:

Python, Typescript, React, Postgres, but Jaah can rewrite itself into any other stack in a few days.
