AI Building Blocks for Indie Makers

You don't need a research team to ship an AI feature. These are the infrastructure pieces solo builders actually reach for — voice agents, web scraping, browser automation, and cheaper fine-tuning — without the enterprise sales call.

Curated by the Ignlab Launch team

  1. 1

    Vapi

    AI

    The fastest way to prototype a voice AI agent that actually answers a phone call.
  2. 2

    Retell AI

    AI

    Similar space to Vapi — worth comparing both before you commit to a voice stack.
  3. 3

    Firecrawl

    AI

    Turns any website into clean, LLM-ready text — the unglamorous plumbing every RAG project needs.
  4. 4

    Browserbase

    AI

    Headless browser infrastructure so your AI agent can actually click around the web, not just read static pages.
  5. 5

    LibreChat

    AI

    Open-source, self-hostable chat UI that works with any model — good if you don't want to build a chat frontend from scratch.
  6. 6

    PromptLayer

    AI

    Version and evaluate prompts like code, instead of editing them in a text file and hoping.
  7. 7

    Unsloth

    AI

    Fine-tune open models significantly faster and cheaper — useful once "just prompt GPT-4" stops being enough.
