Changelog

A new public leaderboard at index.stuntdouble.io that scores hundreds of real websites on how well they work for AI agents. Compare providers side-by-side, explore scoring methodology, and see how your domain stacks up.

Domain owners can now sign in, edit metadata, re-run scoring on demand, and manage how their site appears on the Index.

A new visual identity rolls out across the app, marketing site, and desktop shell — refined typography with our new Untitled Sans and Serif fonts, brand icons, a warmer palette, and more considered hover and surface states.

Sign-in, invitations, and notification emails now match the Marquee look, so every touchpoint feels like one product.

A fresh cut of the macOS desktop app shipping the latest product work, including the Marquee refresh, improved project dashboard, and pull-to-refresh on touch devices.

On phones, the Index leaderboard now sits above the stats rail so the rankings are the first thing you see.

Run a design review across any page or prototype and watch multiple actors annotate it from their own perspective. Feedback lands on a shared canvas where you can pan, zoom, resolve comments, and re-run the review after making changes.

Create a project directly from a Figma file. Connect Figma via OAuth and bring your designs into Stunt Double so actors can review screens before you ship a single line of code.

Visualise how the pages of your product connect to each other. Stunt Double crawls your site — including links tucked away in the footer — and builds an interactive map you can explore.

Stunt Double now follows your operating system theme by default, and you can override it any time from your account settings. Dark mode, light mode, or whatever your Mac is doing right now.

The mobile drawer now mirrors the full desktop sidebar, so every navigation option is a tap away when you are working from your phone.

Workspace activity — new feedback, completed checks, fresh insights — now streams in more reliably and with less lag, keeping everyone on the same page without needing to refresh.

Page skeletons now match the layout you are about to see, so navigating between sections feels instant and less jarring.

When you open an insight, its parent project stays expanded and the Insights nav item is highlighted, so you always know where you are.

A signed and notarised native macOS app. Runs as a universal binary on both Apple Silicon and Intel Macs, with automatic OTA updates.

A download button in the navigation always points to the latest release. No manual version tracking needed.

Submit feedback from anywhere in your workspace. The form is always accessible, so your team can share thoughts without leaving what they are working on.

See the status of every piece of feedback you have submitted directly from your account page. Know what has been acknowledged, actioned, or resolved.

Reduced from 32 MCP tools to 23 without losing functionality. Cleaner interfaces, fewer redundant calls, and faster agent interactions.

Creating a checklist from a project now prefills the URL and name automatically, saving setup time.

Create goals directly from insight reports and dynamically link them as new findings come in.

Design system reviewer, security auditor, legal reviewer, and compliance checker join the cast, expanding what actors can specialise in.

Resolved an intermittent issue where an error was displayed during sign-in code entry.

Run browser workers behind your own firewall or VPN. Available on Enterprise plans.

Link your GitHub repositories to workspaces and bring actors into pull request reviews. Stunt Double can now surface user perspective directly in your code review workflow.

Connect your Linear workspace and use Stunt Double as an agent inside Linear. When an issue is assigned to an actor, it gets to work automatically.

Connect Figma via OAuth and let actors interact with your designs before a single line of code is written.

A native Stunt Double desktop app for macOS. Now available for download.

Regenerate AI insight reports after making changes, with a full version history so you can always compare what changed and why.

Assign and configure self-hosted workers directly from the workspace dashboard.

Click anywhere on a live prototype or product to drop a pin, write a comment, and start a thread. Replies, notifications, and screenshot attachments are all included.

Reply to any feedback comment and get notified when someone responds. Keeps conversations in context rather than scattering them across tools.

Comments are pinned to specific page versions using a content hash, so feedback stays anchored even as pages evolve.

The chat assistant can now query your projects, goals, issues, checklists, and feedback in real time, giving answers grounded in what is actually happening in your workspace.

View feedback for a specific page or route, including full support for single-page apps that update the URL without a full reload.

Optimised font loading and asset delivery. The app opens noticeably faster, especially on mobile.

The mobile bottom bar now surfaces project views as primary tabs, making it much faster to move between Goals, Checklists, Feedback, and Workflows on small screens.

AI-generated insight reports synthesise feedback and research into structured findings. Now available to all users as a public beta.

Connect individual feedback items and insight reports to product goals, so you can track how user research supports (or challenges) what you are building towards.

Prominent stats, a two-column layout, and an activity feed give you a clear overview of what is happening across a project at a glance.

The goal detail view now uses collapsible sections and inline feedback search, making it easier to focus on what matters when working through a goal.

See a summary of every project directly from the workspace home, without clicking into each one.

The feedback feature is now available to all users.

Sign in and sign up are now the same step. Enter your email or use Google, and an account is created automatically on first use. No separate signup page needed.

A new split-panel layout on login and signup, with feature highlights on the left and the sign-in form on the right. Cleaner and more confident.

The feedback dashboard now has three goal-oriented views: onboarding for first-time setup, page-grouped review for regular use, and dedicated settings.
