Turn your commits into content that grows your audience.
Postner reads your GitHub activity, understands what you actually built, and drafts LinkedIn and X posts in your voice — so shipping becomes marketing without you doing the marketing.
Spent the week getting paged by one customer's script hammering our API. Today I shipped usage-based rate limiting — sliding window, per API key, with clear 429s and a Retry-After header instead of silent drops. Small fix, but it's the difference between "our API is unreliable" and "our API has limits, and tells you what they are."
Shipped rate limiting on the public API today. Per-key sliding window, proper 429s, Retry-After headers. No more one bad script taking down the whole thing for everyone else.
Built for solo founders, indie hackers, and open-source maintainers.
You can ship. Marketing is the part that stalls.
Most developers and technical founders can build great products but struggle to market them — content creation, social strategy, audience growth, and brand positioning aren't the job they signed up for. So promising products stay invisible, no matter how solid the engineering is.
Your build activity, turned into content — without the manual work.

The hard part isn't writing the post. It's knowing what's worth posting — and how to say it.
Narrative grouping
We cluster related commits into one coherent story, not fragmented noise.
Intent inference
We read across commits to understand what problem you were solving — not just what changed.
Voice calibration
Output reflects how you actually write, not how an LLM defaults to writing.
Platform awareness
LinkedIn gets a reflective, lesson-framed post. X gets something punchy and direct. Same work, shaped per platform.
Smart filtering
Dependency bumps and routine chores never become content. Meaningful progress does.
Improvement over time
The more you use it, the better it sounds like you — and the better it knows what performs.
We read the industry too — not just your repo.
Postner ingests 15+ RSS feeds — TechCrunch, Hacker News, Anthropic, OpenAI, and more — and drafts a post whenever something's genuinely relevant to what you're building. It lands in your review queue right alongside your commit-based drafts.
15+ feeds, watched around the clock
Someone just open-sourced a vector DB and it's already #1 on Hacker News. If you're evaluating retrieval infra this quarter, worth a look before you build your own.
Every draft lands in a queue. You just swipe.
Commits and relevant industry news both flow into the same review queue — nothing is generated one-off per commit. Approve a draft and we schedule it for the time we recommend; skip it and it's gone.
Stripe webhooks now retry with exponential backoff instead of giving up after one failed delivery. 5 attempts, up to 60s apart, dead-letter logged if they all fail. No more silently out-of-sync subscriptions.
