[Web, Beta] Slack app for previewing HTML/Markdown files in-channel

I'm looking for early users/testers for a small Slack app: HTML in Slack.

Product link: https://htmlinslack.com/

The problem I'm trying to validate: teams are sharing more planning docs, research docs, mini apps, prototypes, dashboards, specs, and AI-generated HTML/Markdown files in Slack, but the handoff is clunky. People download files, open them locally, screenshot them, or lose context in threads.

Current flow:

  • Drop a .html or .md file into a Slack channel
  • Get back a hosted preview link
  • Slack unfurls it with a screenshot/preview
  • Teammates can review it in context instead of passing files around

I'd really appreciate feedback from Slack-heavy teams, founders, product people, or anyone using Claude/Cursor/v0 for internal artifacts:

  1. Is the use case clear from the page?
  2. Would you use this for non-sensitive internal docs/prototypes/mini apps?
  3. What trust/security concern would stop you from installing it?

Mainly trying to validate positioning and understand objections before adding more features.
