Agent Runner
Agent Runner lets you build, version, and deploy AI prompt chains from a node-based visual editor instead of scattering prompts across code files. Connect your OpenAI, Claude, or LLaMa accounts, chain prompts together, wire in external APIs, and call finished workflows from your own apps through a REST API. It sits in the developer tools category because the whole product revolves around prompt lifecycle management for engineering teams.
Most workflow builders treat prompts as one step in a larger automation. Agent Runner centers the product on prompt lifecycle management: centralized editing, branch-based versioning for development, testing, and production, and deployment swaps that do not require code changes. The platform also ships 180+ API integrations (Slack, JIRA, Grafana, Typeform, and others) for chaining data between prompt steps, which is a broader connector library than typical prompt-only tools advertise.
It targets prompt engineers, AI developers, and product teams at startups and SMBs who need to move fast without losing track of prompt versions. The team behind SAAS First and MillionVerifier built it as a cloud-only platform with team roles, in-platform testing, performance logs, and GDPR-compliant key storage with 2FA.

What is Agent Runner?
Agent Runner is a visual prompt engineering platform for building, versioning, and deploying AI prompt chains. You design workflows in a node-based editor, connect models like OpenAI and Claude, and call finished chains through a REST API from your own applications.
Which AI models does Agent Runner support?
Agent Runner connects to OpenAI, Claude, and LLaMa through your own API accounts. You link model credentials once in the workspace, then chain prompts across those models inside the visual editor without rewriting integration code for each step.
Is Agent Runner free to use?
Agent Runner offers a free account signup at app.agentrunner.com. The marketing site does not publish paid plan prices, so the documented entry point is the free account on agentrunner.com.
Does Agent Runner have an API?
Yes. Agent Runner exposes API access to individual prompts and full prompt chains. The platform includes sample code for popular programming languages so you can call workflows from your existing backend without rebuilding orchestration logic.
Can teams collaborate on Agent Runner?
Agent Runner supports team collaboration with member roles, version comments, and shared workspaces. Multiple teammates can edit prompts, review branches, and test chains in the same cloud project rather than passing prompt files around manually.
How does prompt versioning work in Agent Runner?
Agent Runner uses branch-based prompt versioning with separate development, testing, and production tracks. You promote a tested version to production and swap the live prompt without changing application code, which keeps deployments tied to reviewed prompt states.
Is Agent Runner cloud-based only?
Agent Runner is a cloud-only platform hosted at app.agentrunner.com. The site describes it as built for high-traffic SMB workloads with encrypted API key storage, OAuth model connections, and two-factor authentication for account login.
