Mergetober: Open Source Month with Cognee | WeMakeDevs x Hacker's Unity

Mergetober is a month-long open source contribution event hosted by WeMakeDevs in collaboration with Cognee. The goal is simple: get paid to contribute to real-world open source software that ships to developers and enterprises worldwide!

Event Overview

Instead of building a hackathon project that gets archived and forgotten, participants build production-ready integrations for Cognee—the open-source memory layer for AI agents. Every contribution merges directly into the real product codebase used by developers globally.

• Duration: October 1 to October 31
• Format: 100% Online & Solo (Individual contributions)
• Cost: Free to participate

What is Cognee?

AI models start fresh with zero context on every call. Cognee is an open-source memory layer that ingests documents, chats, code, and data, turning them into an interconnected knowledge graph so AI agents can reliably remember and reason across sessions.

The Challenge: Build Integrations

You can contribute in two ways:

• Path A (Pick an Existing Issue): Choose an open issue labeled INTEGRATIONS and hackathon on the Cognee GitHub repository (e.g., GitLab, Linear, Elasticsearch, Postman, AWS S3, ClickUp).
• Path B (Propose a New Integration): Propose a brand-new integration that Cognee doesn't support yet by opening a new GitHub issue (up to 5 issues max).

Note: Alongside each PR, contributors must publish a short blog post (Substack, Dev.to, Medium, etc.) explaining how the integration works in the real world.

Prizes & Rewards (Total Prize Pool: $5,000+)

• Top Contributor Prize ($2,000): Choice of an iPhone Duo, MacBook Pro, or $2,000 in cash awarded to the person with the most merged contributions.
• Merged PR Lucky Draw ($100 × 20): $100 cash prize awarded to 20 randomly selected individuals from everyone who successfully submits a merged PR.

How to Participate

• Pick an Issue: Browse open integration issues on the Cognee repo, comment with your approach, and get assigned by @NMZivkovic before starting.
• Build & Open PR: Follow the Cognee integration guidelines and open your Pull Request during October.
• Write a Blog Post: Share a guide or real-world use case for your integration.
• Submit: Fill out the submission form on WeMakeDevs with your PR and blog post links (up to 5 active PRs allowed at a time).
