Built for these decisions.
If any of these are your question, this is the tool.
Where do we even start without breaking the page next week?
โ The plan picks the lowest-risk file first. Design tokens in a single CSS variables block, then one shared button component, then the marketing pages. The team gets a green PR in week 1, not a rewrite.
Can we extract a real design system from this without a designer in the room?
โ The extraction pass groups duplicate utility chains under shared names. Card, surface, stack, divider. The output is a CSS module skeleton with the names already chosen so the designer can rename them after, not block the work now.
Give us one plan with the order, not two more opinions in the thread.
โ Pick one target on the form. Tailwind 4, CSS modules, SCSS, or vanilla with custom properties. The plan ships a single schedule that names the migration path. The opinion war ends on the page, not in the channel.
Can we pull the variables out before any component work?
โ Week 1 is tokens only. The plan extracts the color, spacing, radius, and typography scale into a single file. The designer reviews the file before any component refactor lands. Single source ships on day three.
Eighteen months of Tailwind, 38 classes on one div, and no plan the team can ship Monday.
Your repo has 18 months of Tailwind class soup. The team hit the ceiling on class name salad and the HN thread that lit it up has 642 upvotes saying everyone wants out and nobody wrote the playbook. You open three components and count 38 utility classes on a single div. The migration plan in your head is a ChatGPT prompt that takes an hour and gives four different answers. The senior asks if we should pull a designer in. The junior asks if we should jump to Tailwind 4 first. The meeting ends with 'let us do it gradually' and nobody opens a PR. Three months later the class soup is 22% bigger and there are two refactor branches in the queue that conflict with each other. The cost is not the refactor. The cost is no plan that names the components first, scaffolds the modules second, and tells the team which file to touch on Monday morning.
Four pieces, one tool.
Each piece ships in the first build for waitlist members. SaaS upgrades layer on top.
Class density analyzer
Paste a single component file or a GitHub repo URL. The analyzer reports utility class count per element, the median and 90th percentile across the codebase, and a heatmap of the 20 worst offenders. Most teams find out their median div has 14 classes and their hero section has 71. The number kills the 'it is not that bad' meeting.

Component extraction with name suggestions
The extraction pass scans for repeated utility chains and groups them under shared component names. Twelve patterns by default. Button, card, input, surface, stack, divider, badge, modal, tooltip, table-row, link, container. Names follow the convention already used in your codebase. BEM, Tailwind-style, or kebab. You pick once on the form.
CSS module and design token scaffold
Output is writable files, not pseudocode. Tokens come out as a single CSS variables block. Components come out as CSS modules or SCSS or vanilla with custom properties. The scaffold compiles. You can paste it straight into the repo and the test page renders. The plan does not stop at advice.

4-week schedule with PR checklist per file
Week 1 lands tokens. Week 2 lands base components. Week 3 lands layouts. Week 4 lands page-level cleanup. Each file has a one-paragraph PR description ready to copy, with the rollback rule on the last line. The reviewer never asks 'what does this change touch'. The answer is in the PR body.
Today's tools don't do this.
A senior dev at $150 an hour spends 5 to 10 hours writing a migration plan from scratch and the team still drifts because the plan lives in a Notion doc nobody updates. A failed refactor branch costs 20 to 40 hours of conflict resolution before merge. The plan and the schedule cost $4.99 once, the bad branch costs $3,000 in payroll.
Web tool. Paste a component file or a GitHub repo URL. Get a class density scan, a top-12 component extraction list with named classes, a CSS module or SCSS or vanilla scaffold that compiles, and a 4-week refactor schedule with a PR checklist for every file. Works in any browser on desktop.
GitHub action that runs the scan on every PR, repo-wide PR generator that opens the week-1 branch for you, multi-file scan with cross-component dedupe, team-specific naming convention import from an existing style guide, Tailwind 4 target with the upgrade path built in.
Auto-applied refactor commits, automatic branch creation, codebase rewrite. The plan is the schedule and the scaffold, not the merge. The team still ships the code, the plan tells them the order.

Solo builder ยท Choppy Toast
This page is a quick vibe-coded probe to test demand and gather feature requests. The actual product, when it ships, will be a polished, hand-built tool, not this scaffold.
For a sense of what "polished and shipped" looks like, here's another product I built: relly.permissionlabs.com.
Honest answers.
Then the page stays live. The waitlist has no expiry. The faster a teammate with the same Tailwind class soup joins, the faster I build it. Bring the senior who keeps approving 38-class divs. That is the engine.
