Early access · built for indie hackers
Larvabot finds the blogs, threads and directories where your side project belongs, drafts personal emails and replies for you to approve, and shows what actually brings visitors, using your own free API keys.
No credit card. No spam. Your larva gets a spot in line.
How it works
Paste your domain. Larvabot reads your homepage, sitemap and key pages, then drafts a profile: who it's for, who you compete with, the tone to use and where to focus. You fix anything it got wrong before a single search runs.
Features
Every project starts with a profile of your site: audiences, competitors, tone and cautions. Edit it, then approve.
Each draft names the exact page and detail it's about, with follow-ups that stop the moment someone replies.
Reddit and Hacker News threads where people ask for what you built, with a friendly reply you post yourself.
A checklist of free directories, launch sites and communities, with copy written for each one and a Done box.
Hard caps on every metered API, checked against what the provider reports. Your free tiers stay free.
A tiny cookieless snippet attributes visitors to emails, threads, directories and backlinks, per project.
Free by design
Paid outreach tools charge you for every search, lookup and email. Larvabot plugs into free tiers you sign up for yourself, chains them with fallbacks, and puts a hard cap on each one, checked against what the provider itself reports.

Our promise
Outreach only works when people are glad to hear from you, so Larvabot is built to be slow, personal and polite.
Nothing goes out on its own. Drafts wait in a review queue until you say yes.
One or two emails a day per campaign by default, inside a weekday send window.
Reply drafts say you built the thing. You post them yourself, or not at all.
Every email offers a one-word opt-out, and a reply stops follow-ups instantly.
SPF, DKIM, DMARC and MX are checked for every sending domain before you start.
API keys are stored with AES-256 encryption and never shown again in full.
FAQ
Larvabot runs on free tiers you sign up for yourself: an AI key (Gemini or Groq), a search key (Tavily or Serper), and optional extras like Hunter, Brevo and F5Bot. The quota guard stops before any free limit is crossed, so usage never costs you money. Early access is free.
Not if it works as designed. It's built for a few hundred people, not thousands: every message is personal, reviewed by you, rate-limited and easy to decline. If you want to blast 10,000 emails, this isn't the tool.
From the pages themselves: author bylines, contact and ‘work with me’ pages, mailto links and contact forms, checked for a working mail server. Hunter's free tier is an optional fallback.
No. Paste your domain, review the profile, add a couple of free API keys and approve what you like. The only copy-paste is a one-line tracking snippet if you want visitor reports.
Yes. Every project runs independently, with its own profile, campaigns, keywords, sender, tracking and reports.
