Questions, answered.

Is ContextNest free?

The CLI and desktop app are free forever, no strings attached. Community Nest is free to start, and needs a free account to run — same as the desktop app. All three let you bring your own model keys instead of using PromptOwl's.

Which install method should I use?

The CLI if you live in a terminal, the desktop app if you'd rather not, the Claude Code plugin if you're already working in Claude Code or Cowork, and Community Nest if your team needs one shared vault instead of everyone syncing their own.

Do I need an account to use ContextNest?

Not for the CLI — it runs locally with no sign-up. The desktop app and Community Nest do need a free account, though you can bring your own keys instead of using PromptOwl's.

Is ContextNest open source?

The CLI is — it's licensed under AGPL-3.0, which is the strict, "copyleft" flavor of open source. Think of it like Apple sharing an iPhone's blueprints for free, but with a catch: if you build your own phone using those blueprints and sell it, you have to publish your blueprints too. You can't take the free version, change it, and lock the changes away. The desktop app and Community Nest use a separate commercial license and aren't open source.

The CLI and Community Nest commands always run the newest npm release — no version management. Requires Node.js 20+. · Runs 100% locally, private by default.
