Let AI agents see cross repo and maintain session memory.
AI coding agents are limited to how autonomously they can work because they have no model of the codebase as a whole. Polygraph is a meta-harness that gives agents what they're missing: Visibility across every repo boundary and memory that survives the session. Connect all your repos, private and public, into a unified dependency graph without moving any code. Resume, reference or build on any session created by any developer, on another machine, even on different agents.
Our founders, Jeff Cross and Victor Savkin, have been building monorepo tooling for over a decade. In the last few years we've noticed that the ergonomics of monorepos have been especially great with AI agents. All your code visible in one place, allowing you or your agents to quickly see the full context it needs to make decisions that won't break your CI when it comes time to merge.
We wanted to bring this to the whole developer tooling community because we know even if some teams use monorepos, it's not realistic to have an entire org on one (unless you're Google.) It started by building a dependency graph - a sort of synthetic monorepo - and then we had to tackle agentic amnesia. Agents are great, but having to re-explain yourself or losing context sucks. Like a game of telephone, it's never the same as being able to stay in session.
We built Polygraph for:
Individual devs: If you're deep in a feature that touches 3 repos, Polygraph will set up all 3 in a single session, manage CI across them, and keep a record of everything your agent did. A week later if you need to fix a bug or go on PTO and want to hand it off to a teammate, they can continue it on their machine without any loss.
Teams across services: If a change to a shared library touches 5 downstream repos, Polygraph lets your agent validate that change across all 5 before a single PR is opened. It then opens and manages the cross-repo PRs and CI together, so the whole change moves as one unit.

Who hunted Polygraph?
Polygraph was hunted by Heidi Grutter. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
