In their own words
Alloy
Alloy is a product prototyping and user-testing platform that can work from a connected codebase or capture pages through a browser extension. With a codebase connected, it can run an app and show changes live in a browser. Teams can make interactive prototypes, share them, run sessions and collaborate. The Free plan includes $5 credits per user per month, unlimited sessions and viewers, and 30+ integrations. Alloy lists Linear, Jira, Slack and Intercom among its integrations. Sessions can be exported, accessed through MCP or turned into GitHub pull requests; teams can also push changes to a pull request and roll them out to customers. The browser extension needs no setup. Connecting a codebase requires admin permissions and about 15 minutes. Free has standard support, Pro has priority support, and Enterprise has 24/7 support. Pro costs $20 per user per month. Enterprise pricing is custom and includes API access, an account manager, custom terms, and SAML + SCIM.
