Your coding agent can ship the fix. Serpkin knows which one.
Serpkin is the SEO teammate for sites built with coding agents. It reads your site and real search data, picks the next SEO task worth doing, hands it to Claude Code, Codex or Cursor, and checks that it worked.
Why it exists
Coding agents made it fast to build a site. They didn't make it easy to get found. An agent can write perfect metadata, but it can't see what people search for, where your pages rank, what Google indexed or whether last week's change helped.
SEO tools have that data, but they were built for marketers reading dashboards, not for an agent working in your repository. Serpkin connects the two: search data in, one concrete change out, and a measured result afterwards.
What we hold ourselves to
- Evidence before claims
Every mission says what it's based on: a site scan, Search Console, rankings or search data. Results are measured against your own baseline and similar pages you didn't change, and we call that correlation, because it is.
- One change at a time
A long audit list rarely gets fixed. Serpkin ranks the work and hands your agent the single most useful next mission, with the files to change and the checks that prove it's done.
- Your agent writes, you decide
Serpkin never edits or deploys your site. Your coding agent makes the change in your repository and a human reviews, merges and deploys it.
- No ranking promises
Nobody controls Google. We'll tell you what changed after you shipped, not what will happen.
The short version
- Works with
- Claude Code, Codex and Cursor, over MCP. Any site works by URL; Next.js, Astro, SvelteKit, Nuxt and React Router routes are mapped to source files.
- Data
- Serpkin's own search data, your site scans and, if you connect it, read-only Search Console access. You never configure a data provider.
- Your code
- Serpkin receives a map of URL paths to file names, not your source code. Your agent key stays out of git.
- Status
- Early access. Prices are proposed and may change before paid plans open.
