AI prototype collaboration for HTML, SVG, and PNG

Turn AI-generated prototypes into review links your team can act on.

ProtoLens helps OPC founders, small teams, and internal product teams review AI-made HTML prototypes without moving files. Comments stay anchored to the prototype and flow back as Markdown for the next AI pass.

Why ProtoLens

Review falls apart at the last mile.

AI teams produce a lot of HTML prototypes, but review usually falls apart at the last mile: people push temporary repos, send zipped files, publish unsafe public pages, or paste feedback back into chat.

One selected area, two comments, and a Markdown feed for the next AI pass.
A prototype with a selected CTA area, anchored review comments, and an MCP call returning the feedback to an AI agent
How it works

Six steps, no staging server.

Install the ProtoLens GitHub App on selected repositories.
Open the ProtoLens dashboard and choose a repository.
ProtoLens discovers reviewable static prototype files.
Copy or open the stable review URL.
Reviewers comment directly on the prototype.
Owners export Markdown feedback or use the MCP server from AI tools.
Built for AI prototype collaboration.

One-person companies, small product teams, internal tool teams, and agent workflows that need fast human review without setting up a full staging system.

MCP for AI agents

Your agents can read the feedback.

ProtoLens exposes an MCP server so AI tools can list prototype files, create review links, read comments, and export Markdown feedback.

Some clients also support short-lived bearer-token configuration generated from the ProtoLens dashboard.

Security and privacy

Designed around GitHub-backed ownership.

Repository access is controlled by your own GitHub App installation.
Prototype files are fetched by repo, ref, and path instead of cloning repositories and running arbitrary code.
Review comments are stored as Markdown-oriented review data tied to the GitHub-backed prototype.
HTML review rendering is sandboxed. JavaScript execution and form submission are intentionally constrained.
Large files may be refused by current safety and resource limits.
