What Sizzy documents
Sizzy is a desktop developer browser. Its public feature pages describe project workspaces, synchronized device viewports, one isolated browser session per device, a unified console and REST/GraphQL API client, docked Chromium DevTools, screenshots and screen recording, terminals, and coding agents that use the Claude Code or Codex CLI installed on your machine.
Fit
Where Blisk fits, and where Sizzy fits
Both tools can be useful. The split below is about the shape of the workflow, not a score.
Blisk is the better fit when
- Devices are emulated in Chromium with native user agents, pixel ratios, and touch events.
- Device sets are built for quick checks and can be shared with a team.
- Screenshots, multi-device screenshots, and screen recording are one click each.
- An error monitor reports page errors across devices while you work.
Sizzy is the better fit when
- Project workspaces restore the repo path, dev server, tabs, and device layout in one click.
- Each device runs in its own isolated session, so you can stay signed in as a different user per viewport.
- A unified console, an API client for REST and GraphQL, and docked Chromium DevTools sit beside the page.
- Terminals, running processes, and coding agents work in the same window as the previews.
- Coding agents run against the actual project, with device screenshots attached as context.
