Turn every feed into aclean publishing pipeline.
Connect unlimited RSS or Atom feeds and auto-publish new items with dedupe protection, image fallback control, first-comment link options, validation checks, and rate limits that prevent bursts.
Works with WordPress, Substack, Ghost, Medium, YouTube feeds, podcasts, and most standard RSS/Atom sources.
RSS automation with safer defaults.
Postly validates feeds on save, checks API access only when creating or updating a feed, and uses rules that keep publishing predictable across destinations.
Built around the actual RSS workflow
Save-time API checks, unlimited feed sources, and automation controls that focus on feed reliability.
Unlimited feed connections
RSS feeds are treated differently from channels.
- RSS Feed connections do not count as a channel
- Users can connect unlimited feeds
- Each feed can be configured independently
API access checked on save
No API key entry is needed inside the RSS Feed UI.
- Check API access only when creating a feed
- Check API access only when updating a feed
- Team plan has API access by default
Feed validation before activation
Only valid readable feeds should be saved.
- Validate feed URL reachability
- Confirm RSS or Atom can be parsed
- Confirm at least one item is available
Everything needed to syndicate cleanly
Strong defaults for dedupe, links, images, validation, and publishing cadence.
Duplicate protection
Prevent reposts using a priority-based dedupe strategy.
- Check duplicates by GUID first
- Then compare normalized canonical URLs
- Use title similarity only as a fallback
Link placement options
Use feed links in the way that best fits each destination.
- Support link in first comment
- Keep the original article URL preserved
- Disable first-comment use on unsupported destinations
Character handling
Keep posts readable when feeds are long or messy.
- Truncate automatically
- Append Read more and ellipsis
- Apply rules after prefix/suffix composition
Image fallback chain
Choose the best available image source before publish.
- Use RSS image first
- Fallback to OG image, then featured image
- Fallback to default image or skip if required
Rate limits and queueing
Avoid burst posting and spread items out.
- Max posts per hour
- Max posts per day
- Spread posts evenly instead of dumping items at once
Broken-link validation
Validate links and media before anything is published.
- Accept successful 2xx responses
- Follow safe redirects to final URLs
- Confirm selected image URL is accessible
Keep the content original, add your publishing rules
Postly preserves the original feed content while letting you shape how it gets published.
Prefix / suffix builder
Add reusable text around the generated post.
- Add a prefix like 🚀 New on the blog:
- Add hashtags or a suffix without editing the title
Per-platform image crop
Control how images are prepared for each destination.
- 1:1
- 16:9
- Auto smart crop
- Center crop
Per-feed destinations
Configure each feed on its own.
- One feed can publish to multiple destinations
- Each feed keeps its own settings and rules
Safe publishing flow
Every item goes through the same ordered pipeline.
- Normalize
- Dedupe
- Validate
- Queue
- Publish
Set it once. Then let the pipeline run.
Postly polls for new items, checks for duplicates, validates content, and publishes under your limits.

Paste an RSS or Atom feed and verify it can be parsed.
Pick destinations
Choose where the feed should publish.
Set rules
