getStack.dev is a website that tracks the tech stacks of more than 33K repositories. It fetches repositories from GitHub (those with more than 1000 stars and recent activity), analyzes them, and surfaces what tools they use: frameworks, languages, bundlers, testing tools, linters, deployment systems, licenses and more.
And it's updated weekly, so you can see how things evolve over time, what gets adopted, what falls out of use, and how tech stacks shift.
The goal wasn't to create another trend report. We wanted something we could actually use when deciding what to learn next, or when evaluating whether a tool has gained real traction. If a dependency shows up consistently across dozens of major projects, that tells me more than any blog post ever could.
