TRAE SOLO gives the agent a broad visual workspace. Polystro gives each workstream a stable local environment around that work.
TRAE SOLO is one of the richer compare pages because it overlaps on visual workspace, browser, terminal, and idea-to-build messaging. The difference is that TRAE SOLO talks like an AI engineer / all-in-one coding agent, while Polystro’s strongest story is still keeping the local workstream attached and stable across projects and sessions.
Where the workflow actually diverges in practice.
Workspace breadth
Polystro
Polystro keeps the local workstream coherent across projects, sessions, routing, browser identities, and services.
TRAE SOLO
TRAE SOLO presents a broad AI workspace with browser, terminal, editor, docs, and plans inside one agent-led surface.
What 'all in one place' means
Polystro
The emphasis is on keeping the real local environment attached and manageable.
TRAE SOLO
TRAE SOLO emphasizes visual orchestration and context-rich execution, but the public material does not prove side-by-side project session visibility.
Cost model
Polystro
You keep your own subscriptions and avoid a product-managed credit system.
TRAE SOLO
TRAE SOLO pricing is product-managed and membership/token based.

Polystro
TRAE SOLO
Parallel agents
Official pages or docs confirm multiple agents or tasks can run at the same time.
Polystro
TRAE SOLO
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
TRAE SOLO
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
TRAE SOLO
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
TRAE SOLO
Multi-project visibility
Official material confirms project switching or multi-project work in the same product.
Polystro
TRAE SOLO
Browser in the workflow
A built-in browser or browser-assisted workflow is confirmed in official material.
Polystro
TRAE SOLO
Browser identity isolation
Separate browser identities, account views, or session isolation are explicitly documented.
Polystro
TRAE SOLO
Local routing and port handling
Ports, forwarding, or local app access are confirmed as part of the workflow.
Polystro
TRAE SOLO
Review and merge flow
Official material confirms built-in diff review, review queue, or merge workflow.
Polystro
TRAE SOLO
Prompting on the go
Away-from-desk continuation, web/mobile access, or similar async continuation is confirmed.
Polystro
TRAE SOLO
Local environment control
The product explicitly centers your machine and the attached local development environment.
Polystro
TRAE SOLO
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
TRAE SOLO
$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 entry point plus paid TRAE membership tiers.
No clear bring-your-own subscription flow on the official pricing pages we reviewed, even though SOLO can use different models per task.
TRAE pricing is product-managed and token / membership based rather than framed as your own direct provider billing.
Closed source
TRAE SOLO sells an all-in-one visual workspace where the agent orchestrates browser, terminal, editor, docs, and integrations.
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.
