Show HN: Modulus – Cross-repository knowledge orchestration for coding agents

Source: Hacker News

Overview

Hello HN, we’re Jeet and Husain from Modulus (https://modulus.so) — a desktop app that lets you run multiple coding agents with shared project memory.

Problems

• Cross-repo context is broken. When working across multiple repositories, agents don’t understand dependencies between them. Even if we open two repos in separate Cursor windows, we still have to manually explain the backend API schema while making changes in the frontend repo.
• Agents lose context. Switching between coding agents often means losing context and repeating the same instructions again.

Solution

Modulus shares memory across agents and repositories so they can understand your entire system. It is an alternative to tools like Conductor for orchestrating AI coding agents, but we focus specifically on multi-repo workflows (e.g., backend repo + client repo + shared library repo + AI agents repo). We built our own Memory and Context Engine from the ground up for coding agents.

Why Build Another Agent Orchestration Tool?

It came from our own problem. While working on our last startup, we were working across two different repositories. Working across repos meant manually pasting API schemas between Cursor windows — telling the frontend agent what the backend API looked like again and again. So we built a small context engine to share knowledge across repos and hooked it up to Cursor via MCP. This later became Modulus.

Future Plans

Soon, Modulus will allow teams to share knowledge with others to improve their workflows with AI coding agents — enabling team collaboration in the era of AI coding. Our API will allow developers to switch between coding agents or IDEs without losing any context.
