Espejo is a session recorder that installs with one <script> tag. By default
it records nothing to a server: it keeps a capped, in-memory ring buffer of
network requests (with bodies), console output, clicks and navigation, and
only uploads that buffer when someone calls espejo.report(...) — the
“report a problem” button. Add data-capture="dom" and it also keeps an
rrweb DOM replay; call startVideo() from a click and it records the screen
too.
Ships nothing by default
mode: 'ring' (the default) never uploads a byte until someone reports a
problem. That is the difference between something you can leave running in
production and something that burns your bucket and your users’ privacy
in a week.
Multi-tenant from the ground up
Every recording belongs to a project, every project to a tenant. The console API, the storage keys and the MCP server all scope through that relationship — never through a list of ids resolved ahead of time.
Redacted before it's written
Authorization headers, cookies, anything that looks like a secret, and every value typed into an input are stripped before the bundle ever reaches the bucket — not after.
Readable by an agent
A built-in MCP server (OAuth 2.1 + PKCE, per-account consent) gives Claude Code or claude.ai five read-only tools to list and inspect recordings — scoped to exactly the projects a person authorized.
Support agent
A support agent that reads the page your visitor is on and can point at things or act for them, with your own chat or with our widget. Read the support agent guide.
