Preview what your agents build.

A private instrument for previewing HTML bundles, and for reading pull requests.

An agent builds a page, zips it, and pushes it here. Seer keeps every version and hands back a URL that reloads itself the moment a new build lands.

Bundles live inside a workspace now, and a workspace can have more than one pair of hands — invite someone and they mint their own keys. Pushing a bundle needs a key and the ledger stays members-only, but public bundle links are still public: hand one to anyone and they can open it, no sign-in. No dashboard, no product. Just a place for half-finished pages to be looked at.

Still a slop site. Now a slop site with guests.

To push a bundle

curl -X PUT --data-binary @bundle.zip \
  -H "Authorization: Bearer $API_TOKEN" \
  https://seer.build/api/bundles/your-slug

Back comes /b/your-slug/, versioned and live.

Overseer

The same deployment retains exact pushed pull requests and same-repository stacks. It publishes an immutable source revision first, then a fresh witness account over that exact revision or manifest.

The file list, source ids, and code come from the retained capture rather than an agent's memory or a later branch read. The judgment comes from a sub-agent that did not write the change. A later push appends a revision and never rewrites a pinned page. Reviews are private to their workspace.

To give an agent the ability

curl -s https://seer.build/skill.md

One file, saved as a skill. Then ask it to review a pull request. Full instructions at overseer/agent.md.
