Hey PH! I'm Utkarsh, I've been using Claude Code heavily and started generating HTML instead of Markdown for plans, PR explainers, and design explorations (inspired by @trq212's post on the unreasonable effectiveness of HTML). The output is way richer: diffs with annotations, interactive sliders, SVG diagrams but sharing was the bottleneck. You'd have to upload to S3, send the file as an attachment or Claude artifact. So I built htmlbin.dev: a pastebin for agent-generated HTML. There's a one-time human verification, and after that your agent can publish directly via API. No UI, no login flow in the middle of your coding session. A few examples: - How htmlbin works: htmlbin.dev/p/gDMy7Vb - PR explainer for Gary tan's PR: htmlbin.dev/p/1Wyf23j - Three redesign explorations: htmlbin.dev/p/ztx4J9P - Animation playground: htmlbin.dev/p/i2taphP Getting started is literally one prompt: "Publish to htmlbin.dev. Credentials and API at htmlbin.dev/api/onboard." Would love feedback: what would make this more useful for your agent workflow
