OpenFang
An open-source Agent Operating System built from scratch in Rust, designed to run autonomous agents on schedules.

Veritrooper
The scraped page content returned for this listing belongs to an unrelated consumer travel app, so no grounded production details about the LLM evaluation platform can be confirmed from the source. Based on validator context, the tool runs batch-mode evaluations against regulated text — tax filings, drug labeling, SEC disclosures, EU AI Act compliance documentation — and produces audit-trail evidence of model accuracy. It operates across vendors, so teams are not locked into validating a single model. Pricing is not disclosed publicly; procurement goes through a sales conversation. No self-hosted option exists, which matters the moment your legal team asks where patient or client data is processed.
