Overview
About CloudBurn
CloudBurn is an innovative cost intelligence platform specifically designed for engineering and infrastructure teams that utilize Terraform or AWS CDK. It revolutionizes the traditional approach to cloud cost management by shifting from a reactive model, where teams only discover financial impacts after deployment, to a proactive model that emphasizes pre-deployment decision-making. The primary challenge it addresses is the lag between infrastructure deployment and the realization of its financial consequences, often revealed weeks later in AWS bills. This delay can lead to unnecessary expenses since resources are already running and changing them post-deployment can be complex and risky. CloudBurn integrates seamlessly into developer workflows, particularly within GitHub pull requests. When infrastructure-as-code changes are proposed, CloudBurn automatically analyzes the differences using real-time AWS pricing data, generating a detailed cost report that is posted as a comment in the pull request. This report provides a clear, line-item breakdown of the monthly cost impact for each new or modified resource, fostering an essential feedback loop that allows teams to discuss, understand, and optimize costs during the code review phase. By embedding cost visibility directly into the engineering process, CloudBurn transforms financial management from a reactive, finance-led exercise into a proactive, integral part of development.
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.
