LevelFour VS Jaah

LevelFour's answer

Engineering, platform, and FinOps teams at companies that run workloads on AWS, Google Cloud, Azure, or Kubernetes and pay for SaaS and AI tools. Finance teams use it to sign off on the bill and to track each saving.

Jaah's answer:

Engineering leaders, teams and solo developers who want to hand real work to AI agents without lowering the bar for what reaches production: teams that care about review, security, governance and keeping code on their own infrastructure.

LevelFour's answer

LevelFour ships the savings it finds. You pick how each change lands: LevelFour applies it in your account with access scoped to that one change, opens an infrastructure-as-code pull request, or hands your team the steps. Savings Audit then checks the next bill and records the saving, the date, and who approved it. You pay Cloud Savings as 30% of what it saved.

Jaah's answer:

Jaah doesn't just generate code; it gets code to production. Every task runs through a staged pipeline and comes back as a pull request that has passed your own tests plus code, security and acceptance review, corporate guardrails, with a report showing the evidence for each acceptance criterion, everything is auditable.

LevelFour's answer

Pick LevelFour when you want one tool to find the waste across AWS, Google Cloud, Azure, Kubernetes, SaaS, and AI, make the change, and prove the result on the bill. Your engineers review cost in their pull requests on GitHub, GitLab, Bitbucket, or Azure DevOps, and your AI agents query it through the MCP server. Finance pays a share of realized savings and owes nothing when the bill doesn't drop.

Jaah's answer:

Coding agents are cheap; trusting their output is the hard part. Jaah carries your standards into every repository, enforces branch protection agents cannot bypass, and keeps every action on record.

LevelFour's answer

Bruno Rocha started LevelFour in November 2025, with co-founders Ana Julia Ghirello and Gabriel Nielsen, to fix a problem he had seen for years working in engineering. FinOps teams set a savings target and handed it to engineering with no strategy and no context, only the number. LevelFour serves both sides of that handoff: FinOps gets visibility and control over spend, and engineers get the tools to ship each optimization in their code or their infrastructure. Dozens of companies, from startups to large enterprises, now run millions of dollars in cloud spend through LevelFour.

Jaah's answer:

Jaah (Just Another Agentic Harness) was built by its own agents, running in its own harness, on tasks its own pipeline handed them, and it still is. Every change to the product is worked by the same pipeline it sells, under the same reviews, and merged the same way. But at its origin it was devised by a team who started to be cognitively overloaded by all the AI agents it was running.

LevelFour's answer

Python and FastAPI for the API and the savings workers, PostgreSQL for each customer's data, React and TypeScript for the dashboard, Next.js for the website, Go for the CLI, and Terraform for the infrastructure on AWS.

Jaah's answer:

Python, Typescript, React, Postgres, but Jaah can rewrite itself into any other stack in a few days.
