Don't see your stack?
The list above is what we explicitly detect and tune prompts for โ but the underlying model has broad exposure to most production error formats. If you paste a log from a niche runtime, ErrorLens will still give you a structured analysis. Let us know what you're using so we can add a first-class card here.
