[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:
- Is the use case clear from the page?
- Would you use this for non-sensitive internal docs/prototypes/mini apps?
- What trust/security concern would stop you from installing it?
Mainly trying to validate positioning and understand objections before adding more features.
