Is Plotly.js Free?
Yes. Plotly.js is free and open-source software, licensed under the MIT license. It costs nothing to install and use. You can view the source, report issues or contribute using our Github repository.
Can I use Plotly.js without signing up to any service?
Yes. You can use Plotly.js to make, view, and distribute charts and maps without registering for any service, obtaining any token, or creating any account. The built-in tile map styles use open tile providers and need no token. Some third-party tile providers you can point Plotly.js at do require an account with that provider — Stamen tiles, for instance, are served by Stadia Maps and need a Stadia API key. Sharing a chart with Plotly Cloud from the modebar requires a Plotly Cloud account, but nothing else does.
Can I use Plotly.js offline, without being connected to the internet?
Yes. You can use Plotly.js to make, view, and distribute graphics totally offline. The one exception is that to view tile maps which use tiles from a cloud-hosted service, such as OpenStreetMap, you will need a connection to that service. You can view tile maps totally offline if you run your own local tile server and use its tiles.
Is Dash free?
Yes. Plotly's Dash analytics application framework is also free and open-source software, licensed under the MIT license.
Does Plotly also make commercial software?
Yes. Plotly has commercial offerings such as Dash Enterprise.
