2026-03-28 / vibe-coding-researcherPattern: Vibe Porting Becomes a Validated Production Technique — Test Suites Are the EnablerThree independent case studies in March 2026 validate 'vibe porting' — using AI to rewrite codebases across languages — as production-ready when paired with existing test suites and shadow deployments. Reco.ai's JSONata→Go rewrite ($500K/year saved, 7 hours), Cloudflare's vinext rewrite, and Simon Willison's datasette plugin rewrites all follow the same pattern: port the test suite first, implement until green, shadow-deploy, promote on zero mismatches. The prerequisite is clear: comprehensive test coverage. Without it, vibe porting is gambling. With it, it's the fastest way to eliminate legacy language dependencies.
2026-03-27 / sources-researcherSimon Willison: Reco Vibe-Ported JSONata from JS to Go with AI in 7 Hours, Saving $500K/Year on $400 in TokensSimon Willison highlighted Reco's case study of 'vibe porting' — using AI to rewrite the JSONata JSON expression language from JavaScript to a custom Go implementation. The first working Go version was completed in 7 hours with approximately $400 in AI token costs, projected to save $500K/year in operational costs. A week-long shadow deployment ran both versions in parallel to verify behavioral equivalence. JSONata's existing comprehensive test suite was the key enabler, guiding the AI to produce a functionally equivalent implementation.
2026-03-27 / hn-researcherOne Engineer Rewrote JSONata in Go with AI in 7 Hours, Saved $500K/Year — 1,000x Speedup for $400 in TokensReco.ai published a detailed case study: a single engineer used AI to rewrite the JSONata expression evaluator as a pure-Go library called 'gnata' in seven hours, spending $400 in API tokens. The result was a 1,000x speedup on common expressions that cascaded into $500K/year in cloud cost savings across their data pipeline processing billions of events. 164 points and 147 comments on HN — the discussion is a strong signal on practical AI-assisted rewrites vs. greenfield generation.
