About
Prefactor is a real-time evaluation, observability, and reliability platform for production AI agents. It scores every run the moment it happens for quality, drift, cost, and data risk, then wires those evaluations into action so a failing agent is caught live instead of only appearing on a dashboard afterward. Teams can observe every model call, tool invocation, and decision as structured traces and spans, run LLM-as-judge, technical, qualitative, and custom evaluations on each step, and attach context from GitHub, Linear, Jira, databases, internal APIs, or other sources as ground truth. When a run crosses a defined threshold, Prefactor can block or throttle it, pause a sensitive action, or route it to a person for approval, modification, or rejection before execution, with every decision logged. The CLI discovers agents without a platform migration, while TypeScript and Python SDKs provide native support for LangChain, Claude, Vercel AI, OpenClaw, and LiveKit.

About
PricingFast is a web-based pricing experimentation tool for SaaS teams that use Stripe. It lets a team connect a Stripe account, select a product price to test, and show a proposed price to a share of new visitors while other visitors continue to see the current price. Experiments use real Stripe payment outcomes to compare revenue per visitor, helping teams evaluate pricing changes based on purchases rather than conversion rate alone. A coding agent can install the tool through MCP, and teams can rehearse a test on localhost before launch. Tests do not go live until a user launches them and can be paused afterward. The product is aimed at SaaS founders who want to test pricing decisions with payment data. It also offers a free test-duration calculator and guides to pricing experiments.
