Poster.ly vs S2P for turning GitHub activity into social posts.
Compare Poster.ly's commit-level Ship & Share scheduler with S2P when the job is turning tagged GitHub releases into approved, brand-safe announcements across 14 channels.
Poster.ly is commit-level
Poster.ly's Ship & Share monitors commits and pushes, filters out chores, and drafts captions you schedule across 11+ platforms.
S2P is release-level
S2P treats a tagged GitHub release or changelog as the trigger, so the news is a real shipped milestone rather than every commit.
Approval and audit are built in
S2P routes each release draft through review and keeps an audit trail back to the tag, which a fire-and-schedule flow does not.

What fires the post
Poster.ly reacts to commits and pushes with chore filtering. S2P fires on a published release, tag, or changelog update.
Who owns the message
Poster.ly leans solo-founder and scheduling. S2P adds a review step so marketing or DevRel can approve company copy before it ships.
Where it lands
Poster.ly publishes to 11+ scheduler platforms. S2P drafts channel-native copy for 14 destinations including Discord, Slack, Mastodon, and Hacker News.

Decision snippet
If you want a post for every meaningful commit, use Poster.ly. If you want each tagged release to become approved, channel-ready announcements with a trail back to the tag, use S2P.When each fits
You can even run both.
Some indie teams narrate daily progress with a commit-level tool and still want a heavier, reviewed push when a real version ships. That is the seam where S2P slots in.
- Choose Poster.ly when commit-by-commit narration is the point and a solo scheduler is enough.
- Choose S2P when releases need brand-voice copy, human approval, and audit across many channels.
- Run both when daily build-in-public lives in one tool and major releases get the reviewed treatment in S2P.
