Just in case all of them are forks from VS Code... I'm pretty much sure you can port the extensions (eg, I used to use VS Code, then I moved to Cursor, then to Windsurf and now I went away and switched to Antigravity but the first 3 were able to install the same extensions)
Thanks for pointing this, I am adding a few extra validations in v 18 (to be released in a few hours) feel free to raise an issue, this is an open source project but I do review each PR and I keep the code as clean as I can... And yes we do use AI but we know what we are doing :)
A bunch of these are popping up because LocalStack changed their free tier and people needed something else.
This isn’t trying to replace all of LocalStack. Just the basic stuff people were using before, and keep it fast for local dev.. If you care about exact behavior or edge cases you still need real AWS. This is more for quick integration tests so you’re not hitting AWS all the time.
What’s different? IDK, you could try the "dozen AI vibe coded shitty local stack alternatives" and post it on your blog
Hello! The target use case is integration testing, verifying that your application calls the right operations with the right data, not production fidelity. For that, MiniStack works well and is free. For anything requiring exact DynamoDB behavior (capacity throttling, consistency window, stream processing), you're right that it's not a substitute. Contributions to improve error fidelity are very welcome (we have pending ProvisionedThroughputExceededException, TransactionConflictException, ItemCollectionSizeLimitExceededException)
If you’re looking for a Localstack alternative, it’s often because you were using the community tier... In that case, Ministack can serve as a drop-in replacement... otherwise, the price reduction in LS might already address your needs
Hello! We won't have the broad coverage that Localstack has... we're not aiming to be the "next Localstack"... just want to keep the core services that were available for free in the LS community up to date. If you’re looking for larger services like MWAA, sorry, but we won't be supporting them.... Most core AWS services don't receive many updates anyway (their APIs don’t change drastically or frequently)
