GitHub Copilot: Partner Agent Apps Now Available in GitHub Marketplace

GitHub Copilot

GitHub launched agent apps, AI agents built by GitHub partners that integrate directly into GitHub workflows and are installable from the Marketplace. The first wave includes nine partners: Amplitude, Bright Security, Endor Labs, LaunchDarkly, Miro, Sonar, PagerDuty, Packfiles, and Octopus Deploy, each offering purpose-built agents for tasks like experiment implementation, flag cleanup, security scanning, and incident management. Developers can trigger partner agents by assigning an issue, mentioning the agent in a pull request comment, or selecting it in the Agents UI. GitHub plans to open agent app creation to all developers in the coming months.

GitHub Marketplace: Agent Apps

GitHub

GitHub Opens the Marketplace to Partner AI Agents

At Microsoft Build 2026, GitHub introduced agent apps, a new category of GitHub App that embeds AI agents from third-party partners directly into developers' existing workflows. The launch represents a significant expansion of the GitHub Copilot ecosystem beyond Microsoft's own agents, transforming the Marketplace into a destination for specialized AI automation.

How Agent Apps Work

Agent apps are installed just like any other GitHub App from the Marketplace. Once an administrator installs and enables the app, the agent becomes available across three interaction surfaces:

  1. Issue assignment: Assign an issue directly to the agent, which then picks it up and begins working.
  2. Mention in pull requests: Tag the agent in a pull request comment to invoke it on a specific task.
  3. Agents UI: Select the agent from the Agents UI and provide a custom prompt to guide its behavior.

This design lets partner agents participate naturally in existing GitHub workflows without requiring developers to leave the repository context or use separate tooling.

First Wave of Partners

Nine partners are available at launch, each bringing a distinct specialization:

  • Amplitude: Implement A/B tests and feature experiments
  • Bright Security: Dynamic security scanning integrated into the PR review cycle
  • Endor Labs: Software supply chain security and dependency risk analysis
  • LaunchDarkly: Identify and safely remove obsolete feature flags
  • Miro: Collaborative planning and diagramming integrated into development workflows
  • Sonar: Code quality analysis and issue remediation
  • PagerDuty: Incident context and on-call workflow integration
  • Packfiles: Package management automation
  • Octopus Deploy: Deployment pipeline management

Building Your Own Agent App

GitHub announced it will open agent app creation to any developer or organization in the coming months, not just launch partners. Teams interested in building internal or commercial agent apps can join a waitlist for early access.

Availability

Agent apps are available today for all GitHub users. Administrator enablement is required for organization-level access.
