The OpenAI Agents API alternative that doesn't fail silently.
Tell Kav the job in plain words. It builds the agents, runs Codex on your ChatGPT plan and has a second agent check every run before it reaches you.
Every run checked, so you don't have to.
A second agent that didn't do the work checks each run against your goal and your checklist before the result reaches you.
- Sent back, not shipped
- A run that falls short goes back with the exact gap. After three tries, you're told what's missing.
- Told when it keeps missing
- A checklist line that fails twice is raised with you.
- A pass rate for every version
- See whether a change to the workflow made it better or worse.
In OpenAI's Agents API, a completed turn doesn't guarantee every tool succeeded, and OpenAI's docs say to inspect the agent's output yourself. A disconnect mid-turn can fail a tool even when the turn completes.
No code to write, no app to run.
Write the job in plain words. Kav builds the agents, draws the steps and sets when it runs, so there's nothing to deploy.
- Steps drawn for you
- Each step shows the app it works in.
- On a schedule or an event
- Or the moment you press Run now.
- Change it by saying so
- Every change is a version with its own pass rate.
In OpenAI's Agents API, your application starts each session, stores its ID and acts on what the session asks for, such as a function call, before work can continue.
Connect each app once. Answer every ask in one inbox.
Kav finds the apps the job needs and asks you to connect each one once. When an agent needs a yes, it waits in your inbox with everything else.
- Any tool you use
- Anything with MCP, OAuth 2.0, an API key or a sign-in page.
- A live browser for sign-ins
- A login or CAPTCHA opens a live browser you clear once. Hand it back and it carries on.
- Sign-ins refresh themselves
- A run never stops on a login that ran out overnight.
In OpenAI's Agents API, your application builds the sign-in screens for the browser, and asks before it opens each new website, public ones included. You add the access token for each MCP server to a vault.
Runs on the ChatGPT plan you already pay for.
Each agent runs Codex on your ChatGPT plan, signed in by you, or Claude Code on your Claude plan. No API key to create.
- Not only OpenAI
- One agent on Codex, the next on Claude Code.
- Or use Kav AI
- Kav AI usage is included on every plan.
- You decide at a limit
- When your plan's limit is reached, wait for the reset or finish on Kavela credits.
In OpenAI's Agents API, you create an API key, and model usage is billed at API rates, with tools and hosted sandboxes at their standard rates.

Common questions.
What is the OpenAI Agents API?
An OpenAI API that gives your application the Codex harness, managed by OpenAI. OpenAI runs the sessions, compaction and recovery, while your application supplies the tools, the environment and the code that starts each session.
Is Kavela built on the Agents API?
No. Each Kavela agent runs the real Codex in its own cloud computer, signed in with your own ChatGPT account. An agent can also run Claude Code on your Claude plan, or use the included Kav AI usage.
Can Kavela use my ChatGPT plan?
Yes. You sign in with your own ChatGPT account, and Codex runs on your plan. The Agents API needs an API key, with model usage billed at API rates.
How does Kavela know a run did its job?
After every run, a second agent that didn't do the work checks the result against your goal and any checklist lines you add, sends back what falls short, and tells you when a line keeps failing.
Do I need to write code?
No. Tell Kav the job in plain words. It builds the agents, connects your apps and sets when the work runs. To change it, say what should change.
How much does it cost?
Kavela starts with a 14-day free trial, no card, then from $30 a month billed annually with Kav AI usage included. The Agents API bills model usage at API rates, plus tools and hosted sandboxes at their standard rates.
