The translator implements a full parsing pipeline (lexer, parser, AST, optimizer) and is available as both a Go SDK for embedding in CI pipelines and automation tools, and as an HTTP server with a Web UI for interactive ad-hoc translation. Zalando used it internally to migrate to Dash0, their new PromQL-based observability vendor, saving weeks of manual engineering work and eliminating translation errors that LLM-based approaches introduced. ## Full article daily.dev links to this article rather than hosting it.
