Convexity is now available in your browser

Mark Hammondon June 29, 2026

Convexity now runs in your browser, and it's completely free to use. You can try it here.

The most powerful features live in the desktop app, which is available to paying customers, but the web app lets anyone build, run, and analyse Convexity models without installing anything on your machine.

We first launched Convexity a little over a year ago. At that time, we deliberately chose to build it as a cross-platform desktop application, because most energy companies handle highly sensitive data and prefer to keep it on their own premises.

For most teams, the desktop app is still the best way to work, and it isn't going anywhere. But people often just want to share a model with a colleague for a quick look, or try Convexity for the first time, and having to install software first slows that down, especially where IT policies are strict, which is exactly the kind of friction a browser version removes.

Open a model in one click

Try it yourself: open PyPSA-GB in your browser with a single click. The open-source GB model loads straight away, ready to explore on the map.

Edit the model visually

PyPSA-GB has more than 3,000 components, which Convexity shows at a glance in its map and tables. You can drag components around, or click on any components like generators, lines, or storage, to edit them instantly in the browser.

Solve a model in the cloud

Solving models takes lots of resources, often more than your local machine can provide. Our cloud solve provides machines with up to 64 vCPUS and 512 GB of RAM for powerful solving with just one click.

Analyse its results

Convexity has a library of plots to understand your results, and to compare scenarios side by side. You can inspect particular time slices over all scenarios, or pull up summary statistics like costs or emissions.

Our desktop app comes with even more powerful features, letting you run local solves with a bundled commercial solver, apply custom constraints to your models, and use our flexible backend Python library pyconvexity to integrate with your own workflows.
