For Indie Hackers

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.

  1. 1

    Connect your account

    Install the extension and open X — it auto-detects your logged-in tab and connects in one click. No password, no cookies, no developer app.

  2. 2

    Set your voice

    Describe your niche, tone, and the accounts or topics worth replying to. Replyburst uses this on every draft.

  3. 3

    Approve & post

    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.
