Upgrade your development foundation with modern error handling and parsing tools. Improve observability, reduce debugging time, and align with current best practices for scalable B2B software.
Explore eris on GitHubA Go error handling library that adds stack traces, structured serialization, and wrap-friendly semantics to errors. Designed for microservices needing rich error context in logs and observability pipelines.
Pricing: Free and open-source (MIT license)
Try rotisserie/eris Free ->A modern, Python-based parsing library that supports both Earley and LALR(1) parsers. Ideal for building DSLs or replacing aging parser generators like PLY with better performance and active maintenance.
Pricing: Free and open-source (MIT license)
Try Lark Free ->A classic implementation of lex and yacc parsing tools in Python. Widely used but largely unmaintained, often found in legacy codebases requiring modernization.
Pricing: Free and open-source (BSD license)
Try PLY (Python Lex-Yacc) Free ->Our free ROI calculator shows payback period & annual savings in seconds.
eris.Wrap adds stack traces automatically and supports JSON serialization, making errors far more useful in production logs and monitoring tools. This is critical for debugging microservices on platforms like Cloud Run or Vercel.
While PLY works functionally, its lack of active maintenance poses risks for security, compatibility, and bug fixes. Teams should plan migration to actively supported parsers like Lark for long-term stability.
Yes, eris is compatible with Go’s standard %w wrapping, so it can interoperate with other error packages. However, consistency across a codebase is recommended to avoid confusion.
