Four of Product Hunt's top six on August 12 are open-source or BYOK replacements for metered AI SaaS.

Dograh #1 at 341 ("the open source VAPI alternative"), Lettertrace #2 at 233 ("track your AI visibility for free, using your own API keys"), Unsloth Desktop #5 at 138, BearDrive #6 at 116 (Product Hunt). Same day, Woxi (a Rust reimplementation of the Wolfram Language running in the browser) hit the HN front page with 122 points. The move isn't "cheaper SaaS." It's removing the metered middleman: vendor keeps the UX and workflow, customer supplies the keys, the model, and the infrastructure. Lettertrace is the purest version, the AI-visibility category has been selling exactly that as a paid analytics subscription with inference cost baked into the seat price. Push the cost to the customer's key and you can be free at zero marginal cost. BYOK as a pricing weapon, not a compliance feature.
