# LocalStack 22 Hacker News commenters recommended LocalStack and 52 criticized it, November 2025 to November 2026. It was recommended in 7 of 13 months; owners who said how long report a median of 7 years (3 owners). **Verdict:** Recommended for running AWS services locally to speed up development and CI testing. Main caveat: after a price change and an archived repo, many users are looking for alternatives. ## Why people recommend it - Fast feedback for local dev and CI (3 comments): "I had some great results building AWS services for local dev as well as CI/CD and testing in GH actions" ([source](https://news.ycombinator.com/item?id=47593669)) "I can stand up all my infra for my teams 14 microservices in under 30s and test my in flight changes" ([source](https://news.ycombinator.com/item?id=47477754)) "it has been fantastic, saving thousands of dev hours by giving our team tighter feedback loops" ([source](https://news.ycombinator.com/item?id=47477677)) - Reliable track record, few compatibility issues (3 comments): "I've been happily using LocalStack for roughly a decade now and haven't run into a single compatibility issue" ([source](https://news.ycombinator.com/item?id=47595732)) "I've used localstack in the past which worked pretty well." ([source](https://news.ycombinator.com/item?id=46136971)) "While Localstack provide a decent solution" ([source](https://news.ycombinator.com/item?id=47473516)) - Stable, high-fidelity S3 service (3 comments): "LocalStack community's S3 service is pretty stable, so I'm doubtful there'll be much parity drift" ([source](https://news.ycombinator.com/item?id=47017477)) "It's runnable within a docker container and has a high fidelity S3 service." ([source](https://news.ycombinator.com/item?id=47007645)) "Often just spinning up `localstack` works well, even if only for S3." ([source](https://news.ycombinator.com/item?id=49711203)) - Extensive parity tests and coverage (2 comments): "IMO much of the product's success was derived from the extensive snapshot + behavioural tests they created to validate parity with AWS." ([source](https://news.ycombinator.com/item?id=50076417)) "they've really helped to improve test coverage" ([source](https://news.ycombinator.com/item?id=50290543)) ## What people warn about - Repo archived, original maintainers gone (4 comments): "The original maintainers are gone, and users will have to rely on someone else to pick up the work, or maintain it themselves." ([source](https://news.ycombinator.com/item?id=47494929)) "They just closed the repo and ran away. If they had that idea all along, I feel like it hasn't be very, let's say, ethical."

([source](https://news.ycombinator.com/item?id=47498286)) "WAY too much. I just need a tiny service that translates common S3 ops into filesystem ops and back." ([source](https://news.ycombinator.com/item?id=47000972)) "in a well-architected piece of software, you aren't getting that much value from them" ([source](https://news.ycombinator.com/item?id=49858500)) - Messy codebase, proprietary API dependence (2 comments): "LocalStack was just a mess of a codebase that couldn't maintain velocity or attract contributors" ([source](https://news.ycombinator.com/item?id=47594230)) "LocalStack, by building a project on top of proprietary APIs, set themselves up to fail."
