Overview
About CloudBurn
CloudBurn is a proactive cloud cost management platform engineered for modern development teams using Infrastructure-as-Code (IaC) tools like Terraform and AWS CDK. It directly tackles the pervasive and painful issue of unpredictable and spiraling AWS bills. The core problem it solves is the lack of cost visibility during the development lifecycle; teams often discover the financial impact of their infrastructure changes only weeks later on their monthly invoice, when remediation is costly and complex. CloudBurn embeds financial intelligence directly into the existing code review workflow by providing real-time, automated cost estimates for every pull request. This empowers developers, platform engineers, and FinOps practitioners to make cost-aware decisions before code merges and deploys to production. Its main value proposition is fostering a continuous culture of financial responsibility, enabling teams to optimize cloud spend from the very first line of code, prevent costly misconfigurations, and achieve an immediate return on investment by catching expensive mistakes early in the development cycle.
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.
