Anthropic's hosted agent harness for long-running, asynchronous tasks: define an agent, pick a sandbox, start a session and stream results.

Harness
Software delivery platform covering CI, CD, GitOps, security testing, feature flags and cloud cost, with a free plan and modular pricing.
What is Harness?
Harness is a software delivery platform that bundles continuous integration, continuous delivery, GitOps, infrastructure as code management and security testing orchestration. Teams pick modules across DevOps, testing, security and operations, such as feature management, an artifact registry, resilience testing, AI security, AI SRE and an internal developer portal. Harness offers a Free plan that includes Harness Open Source and Litmus Chaos with community support, an Essentials plan sold as an all-in-one DevOps bundle, and a fully modular Enterprise plan with premier support. Essentials and Enterprise are priced by quotation through sales. A newer unit-based Flex Pricing model, in limited availability, charges per Harness Subscription Unit: $0.75 on Essentials and $1.25 on Enterprise, and every Free account gets 1,000 free units a month. The platform connects to tools like GitHub, GitLab, Bitbucket, Jenkins, Kubernetes and the major clouds, which makes Harness a fit for platform and DevOps teams that want one place for pipelines.
Use cases
