visualice: every page and UI state of your site, on every device

Point your agent at a website and visualice catalogues every page and every state those
pages can be in, on every device you configure: open menus and modals, but also form
errors, a cart with items in it, signed-in views and multi-step flows. Then you browse
them all on one zoomable canvas.

Explores like a QA reviewer. The crawler maps the pages and the obvious states, then
an agent works through each kind of page and finds the ones a crawler can't.
Repeatable without the agent. Every state is saved as a recipe the engine replays,
so reruns are fast and identical, and CI can recapture the whole catalogue on every
deploy with no agent involved.
Shows what users see. Pages are captured one screen at a time, as a user scrolls, so
sticky headers, cookie bars and modal backdrops look the way they really do.

The visualice viewer: the home page of a demo site, with its search, subscribe and menu states on desktop and mobile

Get started with Claude Code

Needs Node 22.18 or newer.

/plugin marketplace add alexdevlabs/visualice
/plugin install visualice@visualice

Plugins from a marketplace like this one don't update on their own unless you ask: turn
it on under /plugin → Marketplaces → visualice → Enable auto-update, or update
by hand with claude plugin update visualice@visualice. The CLI also says when a newer
version is out.

Then run /visualice https://your.site, or just ask Claude to "run visualice on
https://your.site". It maps the site, shows you the plan (the kinds of page, how many
screenshots, anything exploring would change on the site) and asks once, explores each
kind of page in parallel, captures everything, and /visualice-view opens the result.

Later runs replay what's mapped and explore only what's new.
/visualice-explore <focus> widens the catalogue on purpose: a section like
/checkout*, or something to hunt for, like form errors.
/visualice https://your.site --quick skips exploring: the crawler on its own.

Other agents (Codex, Cursor, Gemini CLI, …): AGENTS.md points them at
the skill, which is plain Markdown and works anywhere. Agents without subagents explore
one kind of page at a time (the explore flow).

Either way, two files appear next to you: visualice.config.json for settings, and
visualice.routes.md, a list of the pages and states found. Edit the list to steer the
next run: add a page it missed, or mark one to skip. Everything else goes in a gitignored
.visualice/ folder.

Without an agent

The engine is a CLI of its own: the quick path, and what CI runs.

npm i -g visualice                  # or run it without installing: npx visualice <command>
visualice doctor                    # checks Node, the browser and the viewer, and fixes what it can
visualice crawl https://your.site   # find pages and states with the heuristics, and screenshot them
visualice serve --open              # browse the results

To…	Run or set
See how big a crawl will be first	`visualice crawl <url> --dry-run`
Recapture without rediscovering	`visualice crawl --replay`
Limit what's crawled	`--max-pages=20 --exclude='/admin/**'`, or `scope` in the config
Capture pages only, no states	`visualice crawl --no-states`
Crawl a site behind a login	a login recipe in the config, then `visualice auth` (guide)
Add devices, browsers or dark mode	`devices` in the config (configuration)
Check accessibility as well	`checks.accessibility: true`
Share the results without a server	`visualice export report/`
Use it in CI	`--replay --json --quiet --fail-on-error` (crawling)

A good split: let your agent build the catalogue once, then have CI run
visualice crawl --replay on every deploy. The explored states live in the site model,
.visualice/crawl-map.cache.json, so commit it with git add -f (or restore it from a CI
cache) next to the config and routes file.

Use it responsibly

Only crawl sites you own or are allowed to test. visualice stays on the target site, follows
robots.txt unless you turn that off, and while discovering it never submits a form or clicks
a control that looks destructive (delete, sign out, pay).
