about this event
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!
Mandatory registration link: https://www.wemakedevs.org/hackathons/mergetober
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 and 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): a $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 a 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).
Official links & resources. Support & community: join the official Cognee Discord for technical guidance and mentor support.
