About OnPremis IA

In-depth, vendor-neutral guides to self-hosted and privacy-first AI coding tools — plus a free LLM API cost calculator to compare provider pricing for your real token usage.

What we cover

We focus on AI coding tools through a specific lens: self-hosted and privacy-first options, and concrete cost engineering for teams that actually pay the bills. Where most coverage chases the biggest managed APIs, we give open-weight and on-prem setups equal, serious treatment.

How we stay independent

The site is reader-supported through recurring affiliate partnerships and, on informational pages, advertising. None of that changes a verdict. Pricing in the calculator is verified against each provider's own page and dated; affiliate links are marked.

The free tool

Our LLM API Cost Calculator is free, needs no sign-up, and runs in your browser after the first load. It exists to answer one question well: what will this actually cost for my usage?
