About

ECC Tools is an open agent harness system designed for GitHub App automation and security management, built within an open-source ecosystem that has earned over 140,000 stars. The core value of ECC lies in helping development teams start from a single repository, seamlessly integrate a GitHub App to receive repository-native intelligent guidance, and scale up with confidence through the AgentShield and rollout layers when collaboration complexity increases. Whether you are an individual developer or part of a large team, ECC keeps your automation workflows safer and more controllable.

Key Features

Native Repository Integration: Once the ECC GitHub App is installed, the system directly reads repository structure and code context to deliver intelligent, context-aware guidance and recommendations to developers.
AgentShield Security Layer: Built-in agent behavior monitoring and permission verification prevent unauthorized actions, ensuring every automated operation stays within defined security boundaries.
Rollout Layered Deployment: Automate policy rollouts gradually by repository, branch, or user granularity, reducing the risk of large-scale changes and enabling smooth canary testing and rollback.
Open Agent Management: Customize agent rules, trigger conditions, and response strategies to flexibly adapt to the workflow needs of different teams.

Pricing & Fees

  • Pricing: Free plan at $0/month for public-repo GitHub App analysis; Pro at $19 per seat/month (yearly billing saves ~17%); Enterprise is custom-priced via sales contact. The open-source toolkit itself stays free.
  • Free tier: 10 analyses per month with 200 commits per run on public repositories, issue-comment triggered PRs from repo history, and community support with no billing setup.
  • Pro plan limits: Private repo analysis, 50 analyses per active developer seat pooled per installation, 1,000 commits per run, AgentShield-backed scanning, and optional metered overage for higher usage.
  • Enterprise plan: Unlimited analyses with 5,000 commits per run, SSO-ready governance and audit logs, custom rules and policy packs, dedicated onboarding with SLA, and org-wide rollout support.
  • Billing: No credit card required to start; cancel anytime via a self-serve Stripe portal. Switching monthly to yearly credits unused monthly time instead of creating a second subscription, and existing Pro installs can be recovered after a machine wipe without repurchasing.

Who It's For

ECC Tools is built for individual developers and small teams looking to streamline repository management with GitHub App automation and cut down on repetitive tasks. It also serves mid-to-large engineering organizations that need unified agent management and security policies across multiple repositories and teams to reduce coordination risk. DevOps and security engineers will find precise control over automation permissions, release pacing, and anomaly response to keep CI/CD pipelines stable, while open-source maintainers managing high-activity repositories can leverage intelligent agents for issue triage, code review, and release management.
