Local models

Schedule previewer

Describe how often something should run and see the next several times it would actually fire.

Agents & workflows

Local or cloud?

Check what matters to you and see which side of the tradeoff it points to — no email, no signup.

Local vs cloud

Why these exist

Varven runs a language model on your own computer, so questions like “what does this filename mean” and “will this actually run when I want it to” come up before you’ve typed a single prompt. Every tool here answers one of those questions directly.

They are free, they need no account, and they run entirely in your browser — nothing you enter is transmitted anywhere.
