Hey Product Hunt! 👋 I’m an indie developer, and I built Silt because I was priced out of the tools I needed. When I was trying to do outbound for my own micro-SaaS, I realized that top-tier lead enrichment tools were charging upwards of $400/month. As a solo dev, that was impossible to afford. I knew the actual API costs from providers like Apollo were much cheaper, so I built Silt to cut out the middleman. Silt is a pure BYOK (Bring Your Own Key) tool. You use your own API keys, and Silt just provides the async queuing, rate-limiting, and UI to process your CSVs seamlessly. No data markups, no hidden fees. 🎁 Exclusive Launch Offer (Lifetime Deal): I'm currently bootstrapping this solo. To celebrate the launch and get early feedback, I’m offering a $49 Lifetime Deal (LTD) instead of a monthly subscription. 🤝 My personal promise to the first 10 users: If you grab the LTD, I will personally jump on a 10-minute text chat with you to help you configure your API keys and run your first batch of CSV data successfully. If we can't get it working, I'll refund you immediately. I'd love to hear your feedback, roast my UI, or ask me anything about the Cloudflare Workers architecture behind it! Let me know what you think. 👇
