If you give Quadratic a try, we'd love to hear your feedback - there's a button in the app :)

Performance and creating a first-class experience supporting coding languages natively... With legacy systems like Excel and Sheets, they are adding piecemeal upgrades with not necessarily the best experience or performance. As we're in the early stages, we're focused on developers, engineers, and data folks who feel frustrated with the technical limitations of legacy offerings.

You can read our license on our GitHub. The "summary section" reads pretty quickly and outlines what is permissible and what is not.

Our last test was ~5 million cells. We're making performance improvements with almost every release. Building on WASM and WebGL, we aim to be highly performant and handle relatively large data sets (not necessarily big data). If you have a data set you'd like to test, we'd love feedback!

JS executes in a web worker.

If you were asking, "Can I use an API to access data in my sheets from other apps/services?" - no, not today, but we'll add that at some point in the future.

Or if you were asking, "Can I query APIs to get data onto the spreadsheet?" Yes, you can do that today in Quadratic with Fetch() in JS or Requests in Python.

We're focusing on performance (built on WASM and WebGL). Quadratic speaks multiple programming languages fluently and executes in the browser on your GPU. We connect natively to popular data sources, are source-available, and can be self-hosted. It's a modern reimagining of what a spreadsheet is and does.

That's one of the reasons we started building Quadratic, it's a spreadsheet where everyone - technical or not can work with data in the same place. With our AI integration, anyone can start writing JS or Python for complex analysis or mix in formulas for simpler computations.

Yes, it’s running in a web worker. It still has access to the browser, so running code in the worker has the same privileges as regular workers. The only communication with the main thread is via socket messages.

Quadratic has been in BETA for quite some time. We're just announcing the release of native JS support. You can use it today for free :)

Is there anything specifically about security you're curious about?

We're also offering a self-hosted version you can deploy on your own cloud, env., or Docker container.

Thanks for the heads-up on that.

Correct, our license is Source Available to be as open as possible while reserving commercial rights, which we believe will ultimately enable us to build the best product for users.
