Indie Hackers: grow on X on autopilot
You're building solo, marketing solo, and support-ing solo. Replyburst handles the "be visible on X" part so you can put those hours back into shipping.

Sound familiar, indie hackers?
The reasons X growth stalls for people doing exactly what you do.
Build in public only works if you actually show up in other people's threads, not just post your own updates into the void.
You're one person doing the job of an entire growth team — engagement always loses to code and customer support.
Momentum dies fast: skip X for a week during a sprint and your reply habit (and your growth) resets to zero.
You don't have budget for a social media manager or an agency retainer just to keep a consistent presence.
Built for how indie hackers actually work
Consistency without a growth team
Replyburst keeps a steady cadence of replies going even during your heads-down build weeks, so your presence doesn't evaporate the moment you get busy.
Built for one-person budgets
No agency retainer, no VA to manage, no hiring. You bring your own AI API key and pay a flat price — the same instinct that makes you build lean applies to your marketing stack.
Compounding reply-based reach
Replying inside high-traffic threads in your niche gets you seen by an audience you didn't have to build yourself — a much faster loop than waiting for your own posts to find an audience.
How it works
Three steps, set up once.

Review AI-drafted replies in your queue, approve the ones you like, and Replyburst posts them on a natural schedule.
Questions from indie hackers
- I barely have time to open Twitter — how much setup does this take?
- About 15 minutes: connect your account, write a short voice profile, and pick a few accounts or topics to engage with. After that it's a daily approval pass of a few minutes.
- Can I use my own OpenAI or Claude API key?
- Yes. Replyburst supports OpenAI (GPT-4o) and Anthropic (Claude) — bring your own key and you only pay Replyburst's flat subscription, never a markup on tokens.
- Does this replace building in public, or work alongside it?
- Alongside it. Replyburst handles the reply side of your presence — the higher-leverage half most indie hackers skip — while you keep posting your own build-in-public updates whenever you have something to share.
