Superset helps you run lots of coding agents in parallel. Polystro goes further by attaching browser state, routing, services, and project context to each workstream.
Superset is one of the closest compare pages because it clearly sells parallel coding agents on your machine. The difference is not whether parallel agents matter. Both products agree on that. The difference is whether the product stops at parallel agent execution or organizes the surrounding local workstream too.
Where the workflow actually diverges in practice.
Parallelization vs attached context
Polystro
Polystro goes beyond worktree isolation and keeps browser state, terminals, routing, and services attached to each workstream.
Superset
Superset strongly supports parallel agents, worktrees, and handoff into an IDE, but its public story stops closer to the agent runner itself.
Side-by-side sessions
Polystro
You can inspect multiple sessions at once, including cross-project work.
Superset
Superset public material confirms concurrency, not simultaneous side-by-side session visibility.
Business model
Polystro
You bring your own tools and subscriptions without Polystro adding an internal credit layer.
Superset
Superset also scores well here, so the real difference is workflow structure rather than billing philosophy.
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.

Parallel agents
Official pages or docs confirm multiple agents or tasks can run at the same time.
Polystro
Superset
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
Superset
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
Superset
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
Superset
Multi-project visibility
Official material confirms project switching or multi-project work in the same product.
Polystro
Superset
Browser in the workflow
A built-in browser or browser-assisted workflow is confirmed in official material.
Polystro
Superset
Browser identity isolation
Separate browser identities, account views, or session isolation are explicitly documented.
Polystro
Superset
Local routing and port handling
Ports, forwarding, or local app access are confirmed as part of the workflow.
Polystro
Superset
Review and merge flow
Official material confirms built-in diff review, review queue, or merge workflow.
Polystro
Superset
Prompting on the go
Away-from-desk continuation, web/mobile access, or similar async continuation is confirmed.
Polystro
Superset
Local environment control
The product explicitly centers your machine and the attached local development environment.

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
Superset
$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 Pro at $20/seat/month.
Yes. Superset is built around bringing your own CLI agents and whatever models/providers those agents support.
Superset says you also pay your agents' API providers directly, with no markup and no credit system.
Open source (Apache 2.0)
Superset is a code editor for AI agents focused on parallel execution, CLI-agent compatibility, isolated worktrees, and opening worktrees in any IDE.
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.
