LocalStack raises $25M to help developers emulate and test cloud apps locally | TechCrunch
LocalStack shifts app development and testing off the cloud and onto developers' local machines, starting with a focus on AWS.
techcrunch.com
We're excited to announce that LocalStack has raised $25 million in Series A funding, led by Notable Capital, with support from CRV and Heavybit 🚀🥳
This marks a pivotal step in our mission to empower developers and help enterprises build faster and more efficiently 🙌

Why does it matter?
Data teams shouldn’t discover scripting or metadata issues only after deploying to Snowflake. The closer local behavior matches production, the fewer surprises you get in staging and CI.
LocalStack for Snowflake 1.7 continues closing that gap. 💪

We also expanded information_schema coverage and added support for commonly used aggregate and bitwise functions.
Plus we made targeted improvements for dynamic tables, window functions with DISTINCT, session variables, and LIKE / ILIKE behavior.

What does that mean in practice?
You can now test more advanced procedural logic locally, including:
· Anonymous code blocks
· IF / ELSEIF / ELSE branching
· Exception handling with SQLERRM and SQLSTATE

What started as “good governance” quietly becomes operational drag.
Many platform and FinOps teams are now re-evaluating whether every early-stage integration test, infrastructure change, or event-driven workflow really needs to hit a live AWS account.

But over time, this often leads to:
· Cloud spend leakage across non-production environments
· IAM policy sprawl that’s difficult to audit
· Increased compliance overhead
· Environments that are hard to reproduce consistently

Running WireMock inside LocalStack environment lets you:
· mock external HTTP APIs alongside emulated AWS services
· keep Lambda, API Gateway, Step Functions, & mocks on the same local network
· run deterministic integration tests fully offline
· eliminate credentials, rate limits, brittle tests

That’s where local testing usually falls apart:

· rate limits
· missing sandbox access
· CI failures unrelated to your code
Today, we published a new Showcase on how to solve this cleanly using the WireMock extension for LocalStack.

A test that passes on one runtime can fail silently—or unpredictably—on another.
That’s why multi-runtime testing requires:
· validating behavior across runtimes, not just one
· isolating runtime-specific failures
· fixing tooling assumptions that only break when runtimes coexist
