# cadence vs mem0

cadence and mem0 share 5 technologies: MongoDB, OpenSearch, MySQL, Postgres, and Elastic. cadence is written in Go and mem0 in Python.

- [cadence-workflow/cadence](https://seerepo.com/r/cadence-workflow/cadence): Cadence is a distributed, scalable, durable, and highly available orchestration engine to execute asynchronous long-running business logic in a scalable and resilient way.
- [mem0ai/mem0](https://seerepo.com/r/mem0ai/mem0): The Memory Layer for AI Agents - Drop-in memory infrastructure for AI agents and apps. Context that persists. Built for production.

| Who writes it | 0.2% of its commits signed by AI. With GitHub Copilot, Claude Code, and Cursor | 3.6% of its commits signed by AI. With Claude Code and Cursor |
| Activity | Last push November 14, 2026, 5,945 commits, 9,556 stars | Last push November 6, 2026, 2,655 commits, 68,877 stars |
| Tests | 872 test files. 83.6% of its code files have a test that imports them | 324 test files. 54.2% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
