# open-code-review vs github1s

open-code-review and github1s share 5 technologies: OpenAI, Anthropic, Preact, Mermaid, and dompurify. open-code-review is written in Go and github1s in TypeScript.

- [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.
- [conwnet/github1s](https://seerepo.com/r/conwnet/github1s): One second to read GitHub code with VS Code.
