Overview
About CloudBurn
CloudBurn is a proactive FinOps and cost intelligence platform designed for engineering teams using Infrastructure-as-Code (IaC) tools like Terraform and AWS CDK. It directly tackles the pervasive problem of unexpected and spiraling AWS bills by integrating cost visibility into the developer workflow. The tool is built for developers, platform engineers, and DevOps teams who want to shift cost governance left, catching expensive infrastructure misconfigurations during code review—before they are ever deployed to production. By automatically analyzing pull requests, CloudBurn provides real-time, line-item AWS cost estimates for proposed changes, posting a clear report as a comment. This transforms cost from a retrospective, finance-team concern into a real-time, actionable metric for engineers. Its core value proposition is preventing financial waste by enabling informed architectural decisions early, fostering a culture of cost accountability, and delivering an immediate return on investment by avoiding costly mistakes that traditionally only surface weeks later on an invoice.
About OpenMark AI
OpenMark AI is a web application for task-level LLM benchmarking. You describe what you want to test in plain language, run the same prompts against many models in one session, and compare cost per request, latency, scored quality, and stability across repeat runs, so you see variance, not a single lucky output.
The product is built for developers and product teams who need to choose or validate a model before shipping an AI feature. Hosted benchmarking uses credits, so you do not need to configure separate OpenAI, Anthropic, or Google API keys for every comparison.
You get side-by-side results with real API calls to models, not cached marketing numbers. Use it when you care about cost efficiency (quality relative to what you pay), not just the cheapest token price on a datasheet.
OpenMark AI supports a large catalog of models and focuses on pre-deployment decisions: which model fits this workflow, at what cost, and whether outputs are consistent when you run the same task again. Free and paid plans are available; details are shown in the in-app billing section.
