Polyscope 0.15 adds multi-server switching and plan mode

• Polyscope 0.15 bundles five core changes: multi-server switching in the desktop app, running Polyscope from a repo’s base path, plan mode for more model backends, split-screen diff view, and commit logs, according to the launch thread.
• The biggest implementation change is model coverage: Polyscope’s plan mode update says planning is “no longer restricted to Claude” and now works with Codex and Cursor models.
• Setup friction also drops in repo-scoped workflows, because the base repository post says developers can start agents “without copying any files.”
• The release adds more desktop-side navigation around active work: the server-switching post shows remote/local server switching from the UI, while the commit log post adds commit inspection that opens Polyscope’s diff view.

Polyscope 0.15 is mainly a workflow release for people running coding agents against real repos. In Marcel Pociot’s launch thread, the headline items are multi-server support, base-repository mode, plan mode for Codex and Cursor models, split-screen diffs, and commit logs. The practical shift is that more of the agent loop now happens inside the desktop app instead of through setup workarounds.

Two of the new controls tighten review and navigation. Pociot’s commit log post says you can inspect commits in the right sidebar, and clicking one opens the Polyscope diff view. Separately, the server-switching post says users with multiple servers can switch between remote and local instances directly in the desktop UI.

The clearest day-to-day change is broader model support. Polyscope’s plan mode update says plan mode is “no longer restricted to Claude” and can be used with “ANY model,” with Codex and Cursor called out explicitly. A later Cursor models post reinforces that Cursor-backed models are now part of the supported path.

Repo setup is also lighter. The base repository post frames the new option around getting “an agent up and running in your repository” without copying files, which makes Polyscope easier to drop into an existing codebase. On the navigation side, the repository selector post adds a CMD+N repository picker with the current workspace repo pinned at the top, and Pociot’s preview URL post says workspaces can expose preview URLs with automatic tunnel URLs on mobile or remote connections.
