Overview
About CloudBurn
CloudBurn is a game-changing FinOps platform engineered to revolutionize how development and infrastructure teams manage cloud costs. It directly tackles the pervasive and costly problem of financial surprises in AWS bills by shifting cost governance left, directly into the developer workflow. Designed specifically for teams using Infrastructure-as-Code (IaC) tools like Terraform and AWS CDK, CloudBurn provides transformative, real-time cost intelligence at the most critical moment: during code review. By automatically analyzing pull requests, it delivers instant, detailed estimates of the monthly financial impact of every infrastructure change before a single resource is provisioned. This proactive approach empowers teams to foster cost-aware development cultures, enabling informed discussions about architecture, resource sizing, and budget alignment prior to deployment. CloudBurn transforms cost from a reactive, post-bill shock into a proactive, integral metric of code quality, ensuring financial efficiency and preventing thousands of dollars in unnecessary overspending with every merge.
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.
