Catapult
Marketing automation for indie app developers
macOS Desktop AppFind where your app's audience is talking, generate authentic community-aware copy, and post it directly — all from one screen. Built for solo developers who'd rather ship features than spend hours on marketing.
Trend Discovery
Scan Reddit, X, and Hacker News for conversations relevant to your app. Surface threads where your app is a genuine answer to someone's question.
AI-Powered Copy
Generate community-aware responses that match each platform's tone. Powered by your local AI CLI — no API keys to manage, no vendor lock-in.
One-Click Posting
Post directly to Reddit and X from Catapult. Authenticate once, then engage with your audience without switching between browser tabs.
Multi-App Management
Register all your iOS and Android apps in one place. Track marketing efforts across your entire portfolio from a single dashboard.
How It Works
Register Your Apps

Discover Opportunities
Catapult scans social platforms for threads where your app is relevant. No spam — only conversations where you can genuinely help.
Generate and Post
AI generates a response that fits the community's tone. Review it, edit if you want, and post with one click.
