Better Slack messages.
A few useful tools.
Build, preview, and customize Slack Block Kit messages. Free to use, with no Fryll account or Slack login required.
Slack Block Kit
Start with an idea, a template, or your own JSON.
Preview & validate
Slack Block Kit previewer
Paste your JSON and see the message as you edit. Find validation errors before they reach your integration.
- Live preview with light and dark themes
- Precise validation errors and suggested fixes
- Copy JSON, download, or open in Slack’s Builder
Describe & refine
AI Block Kit generator
Describe the message you need, then refine the layout in your own words. Keep control of the JSON at every step.
- Complete message layouts from a prompt
- Follow-up instructions and editable JSON
- Cancel a request or undo a revision
Browse & customize
Slack Block Kit templates
Start with a thoughtful example for deployments, incidents, customer updates, or team workflows. Make it yours in minutes.
- 17 templates with useful variants
- Editable fields and accessible fallback text
- Sending examples and interaction setup
All three tools share the same editor. Move from a template to the previewer or AI generator with your edits intact, then export the JSON for your integration.
