Scalebrowser is a desktop browser platform built specifically for AI agents. It gives each agent its own isolated browser profile with a persistent identity, so automations can stay signed in between runs instead of starting from a blank session every time. Agents connect over MCP, Python and Node SDKs, a REST API or direct CDP, and every tool call is captured as a step with a result and a screenshot.
Whimsical is a collaborative visual workspace that combines diagrams, flowcharts, mind maps, wireframes, documents and whiteboards on one infinite canvas, with AI tools that turn a prompt into a structured visual in seconds.

Persistent profile identity
Each profile is generated from a seed so its identity, cookies and logins persist across restarts, and sites see the same returning visitor rather than a new device.
Isolated browser profiles
One browser per profile means separate logins, cookies and devices that share nothing, making multi-account automation safe to run in parallel.
Built-in sign-in and 2FA handling
Agents get through username and password forms, email confirmation codes, TOTP and SMS two-factor codes, passkeys and permission prompts without stalling.
Human-like input and captchas
Press-and-hold, image grid, slider and rotation captchas are solved through human-like input rather than third-party solving keys.
優勢與優點
+Strong focus on persistent, isolated identities so agents stay logged in across runs
+Broad integration surface covering MCP, Python/Node SDKs, REST and direct CDP
+Built-in handling of logins, email codes, TOTP, SMS, passkeys and captchas
+Token-efficient page reading that only reports what changed between steps
+Detailed run trails with screenshots make debugging agent runs easier
限制
–Requires installing a desktop app and running it on your own machine, so it is not a purely cloud-hosted service
–Free tier excludes schedules, webhooks, sync and phone approvals
–Paid tiers meter concurrent browsers, machines and profile counts, which can raise costs for large fleets
–Advanced anti-detection features may raise compliance responsibility with target platforms
Whimsical
Whimsical is a collaborative visual workspace that combines diagrams, flowcharts, mind maps, wireframes, documents and whiteboards on one infinite canvas, with AI tools that turn a prompt into a structured visual in seconds.
Prompt-to-visual AI tools
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
One infinite canvas
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Real-time multiplayer editing
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Wireframing and user flows
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
優勢與優點
+AI generates native, editable Whimsical objects rather than flat images
+Single workspace replaces separate diagramming, whiteboarding, wireframing and docs tools
+Unlimited viewers and guests are free on every plan, including Free
+
Fast, lightweight editor with an excellent template library
+Strong collaboration features — live cursors, object comments, version history
+Serious security posture: SOC 2 Type 2, GDPR/CCPA support, SAML SSO and SCIM on Business
限制
–Free plan caps you at 50 board objects and 50 doc blocks per month plus export watermarks
–AI credits are limited per seat and extra credits cost more
–Advanced admin and security features are locked behind the Business tier
–Very large, asset-heavy boards can feel slower than focused single-purpose tools
–No full offline mode; the desktop app still depends on connectivity
