How do most AI SaaS tools charge (credits vs monthly subscriptions)?

Most modern AI SaaS tools use hybrid pricing: an entry-level monthly subscription that includes a fixed monthly credit quota, paired with pay-as-you-go top-ups for high-volume LLM inference and generation.

Can I find free and open-source AI tools on SaaSearch?

Yes. You can filter listings by pricing model (Free, Freemium, or Paid) and tech stack. Many makers provide 100% free open-source tiers with self-hosting instructions and MIT licenses.

How are MRR and user counts verified for AI startups?

SaaSearch integrates directly with Stripe and Paddle telemetry to verify recurring monthly revenue, growth velocity, and active users, ensuring figures are authentic rather than estimated.

How can AI developers launch their product on SaaSearch?

Founders can submit their AI application for free. Once you add the verified SaaSearch launch badge to your homepage, your listing is published immediately to today's launch leaderboard with zero queue delay.
