Cursor helps you work with agents inside its coding environment. Polystro keeps the broader local workstream from turning into a mess.
A lot of buyers will compare Polystro with Cursor because Cursor has the mindshare. The real split is not editor versus editor. It is whether you mostly need a strong AI coding surface or you need the whole local workstream to stay coherent across browser, routing, terminals, services, and projects.
Where the workflow actually diverges in practice.
Environment scope
Polystro
Polystro organizes the whole local workstream: browser state, terminals, services, routing, and project context.
Cursor
Cursor Glass stays centered on the coding environment and agent workspace inside the Cursor product.
Session visibility
Polystro
You can keep same-project and cross-project agent sessions visible side by side.
Cursor
Glass public material supports multiple agents and repositories, but not side-by-side session visibility in the Polystro sense.
Switching cost
Polystro
Switching workstreams brings the attached browser, terminal, and runtime context with it.
Cursor
Cursor focuses more on orchestrating agent work than on linked switching of the surrounding local environment.
Where the confirmed capability set differs.
This is the faster way to read the comparison: what we could confirm in the official material that actually matters to this workflow.

Polystro
Cursor
Parallel agents
Official pages or docs confirm multiple agents or tasks can run at the same time.
Polystro
Cursor
Same-project side-by-side sessions
Can you see multiple agent sessions from the same project at once, side by side, instead of switching through a tab or thread list to inspect them one at a time?
Polystro
Cursor
Cross-project side-by-side sessions
Can you see agent sessions from different projects at the same time, side by side, instead of switching projects or session lists to inspect them?
Polystro
Cursor
Context-linked switching
When you switch projects, workstreams, or worktrees, do the browser, terminal, and attached context switch with you as one linked unit?
Polystro
Cursor
Multi-project visibility
Official material confirms project switching or multi-project work in the same product.
Polystro
Cursor
Browser in the workflow
A built-in browser or browser-assisted workflow is confirmed in official material.
Polystro
Cursor
Browser identity isolation
Separate browser identities, account views, or session isolation are explicitly documented.
Polystro
Cursor
Local routing and port handling
Ports, forwarding, or local app access are confirmed as part of the workflow.
Polystro
Cursor
Review and merge flow
Official material confirms built-in diff review, review queue, or merge workflow.
Polystro
Cursor
Prompting on the go
Away-from-desk continuation, web/mobile access, or similar async continuation is confirmed.
Polystro
Cursor
Local environment control
The product explicitly centers your machine and the attached local development environment.
Polystro
Cursor
Cross-platform desktop
Check for macOS + Windows + Linux, dash for 2 of the 3, cross for only 1 platform or no public confirmation beyond that.
Polystro
Cursor
$9/month billed yearly ($108/year) or $12 monthly
Yes. Bring your own CLI subscriptions and agent setup, and use the models those tools support without Polystro adding model credits or markup.
You pay Polystro for the desktop workflow. Your model and agent usage stay with the providers you already use.
Closed source
Free tier plus paid plans from $20/month to $200/month and team plans.
No clear bring-your-own subscription model. Official pricing frames usage through Cursor plans, even when multiple model providers are available.
Cursor plans include agent usage and bill around model usage inside the Cursor pricing system.
Closed source
Cursor is moving from AI editor toward a multi-agent interface, especially with Glass and the 2.0 parallel-agent workflow.
The compare-page goal is not to pretend every product is the same. It is to show where Polystro's wedge starts: the local workstream itself. That means the browser, routing, services, terminals, and project context stay attached while multiple agents work in parallel.
