Show HN: Rejit – a regex engine that can't be ReDoS'd (Pike VM, pure Python)

Description and use

**Rejit Regex Engine Summary**

Rejit is an open-source regex engine that provides a unique solution to the ReDoS (Regular Expression Denial of Service) vulnerability. Developed using the Pike VM and pure Python, Rejit is designed to be safe and efficient. Its value lies in its potential to be used in workflows where ReDoS attacks are a concern.

**Value Proposition**

Rejit's value proposition is its ability to prevent ReDoS attacks, making it a useful tool in specific workflows where regex is used extensively. However, its adoption path requires careful consideration due to the limited quality signals and sparse integration notes.

**Practical Adoption Path**

To adopt Rejit, developers should:

1. Review the project's README to understand its usage and limitations.
2. Inspect the project's activity to assess its maintenance and development pace.
3. Verify the project's license, documentation, and issue tracking to ensure it meets their needs.
4. Perform dependency and maintenance checks before integrating Rejit into production.

**Production Readiness**

Rejit is considered production-ready for internal workflows or prototypes, but it may not be suitable for large-scale production environments due to its limited quality signals and sparse integration notes. Before using Rejit in production, developers should carefully evaluate its risks and perform thorough testing

Use in a workflow

Show HN: Rejit – a regex engine that can't be ReDoS'd (Pike VM, pure Python) may be useful when its README and activity match a concrete workflow.

Limitations and review notes

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.
