# open-code-review vs memos

open-code-review and memos share 3 technologies: net/http, OpenAI, and MCP. Both are written in Go.

- [alibaba/open-code-review](https://seerepo.com/r/alibaba/open-code-review): Secure, fast, efficient, battle-tested at Alibaba's scale. Hybrid architecture code review tool: deterministic pipelines + LLM Agent, precise line-level comments, built-in multi-language ruleset (NPE, thread-safety, XSS, SQL injection), OpenAI & Anthropic compatible.
- [usememos/memos](https://seerepo.com/r/usememos/memos): Memos is an open-source, self-hosted note-taking app that brings your everyday thoughts together in a personal timeline. Your data stays yours, and you choose what to keep private or share.

## What they share and what sets them apart

- In common: net/http, OpenAI, MCP
- Only in open-code-review: Anthropic
- Only in memos: React, Vite, Postgres
