How much does ECC cost?

ECC has a freemium pricing model. The GitHub App is free for public repositories. Pro tier costs $19 per seat per month for private repos, and Enterprise tier offers advanced governance and SSO. The open-source toolkit is free to use locally.

ECC offers a free plan: the open-source toolkit is free, and the GitHub App is free for public repositories. For private repos, Pro starts at $19/seat/month. A free trial may be available for Pro/Enterprise.

What is the difference between ECC and LangChain?

ECC focuses on agent harness optimization for coding agents like Claude Code and Cursor, with built-in security and governance. LangChain is a broader framework for building LLM applications. ECC offers 261 skills, 102 security rules, and cross-harness support, while LangChain emphasizes flexibility and integrations.

ECC is best for developers using coding agents who need security and policy enforcement, teams using Claude Code, Codex, Cursor, or OpenCode wanting cross-harness portability, engineering organizations automating repo workflows via GitHub App, and enterprises requiring governance, SSO, and audit trails.

Who should avoid using ECC?

Avoid ECC if you are a beginner looking for simple plug-and-play agent without configuration, use non-supported agent harnesses, prefer a fully managed cloud solution with no local setup, or need extensive integrations beyond GitHub and the listed agent harnesses.

What are the key limitations of ECC?

ECC is limited to supporting only four agent harnesses: Claude Code, Codex, Cursor, and OpenCode. It requires local setup for the control-plane and may have a learning curve. Integration options are primarily GitHub and the listed harnesses.

What integrations does ECC support?

ECC integrates with Claude Code, Codex, Cursor, and OpenCode as agent harnesses. It also integrates with GitHub via a GitHub App for repo-native automation and PR scanning. No other integrations are listed beyond these.

Is ECC easy to set up?

ECC has a moderate learning curve. The open-source toolkit can be used locally with minimal setup, but the control-plane (ECC 2.0) and GitHub App require configuration. Beginners may find it complex due to the number of agents, commands, and security rules.

Is ECC good for enterprise teams?

Yes, ECC is designed for enterprises requiring governance, SSO, audit trails, and security. The Enterprise tier offers advanced features. However, teams must use supported harnesses and may need local setup.

Does ECC have a trial version?

ECC's open-source toolkit is free to try without time limit. The GitHub App is free for public repos. For private repos, Pro/Enterprise tiers may offer a free trial; check the official site for current offerings.

What are some alternatives to ECC?

Alternatives include LangChain (broader LLM framework), AutoGPT (autonomous agents), and other coding agent toolkits. ECC's unique value is its focus on security and cross-harness support for four specific agent harnesses.

Is ECC good for security-conscious development teams?

Yes, ECC includes AgentShield with 102 security rules, token optimization, and operator review. It provides session visibility and policy enforcement, making it suitable for security-conscious teams using supported agent harnesses.

ECC is the most comprehensive open-agent system for teams using Claude Code, Codex, Cursor, or OpenCode. Its three-layer architecture — OSS toolkit, AgentShield security, and ECC 2.0 control plane — delivers real cross-harness portability and policy enforcement. The free tier is generous for public repos, but Pro pricing at $19/seat is reasonable for private repo automation. Best for advanced teams; beginners may find the setup heavy.

About ECC

FreemiumAdvancedAPI availableCLI · Plugin · API

ECC is an open-source agent harness system that secures and optimizes coding agents across Claude Code, Codex, Cursor, and OpenCode. Designed for developers and engineering teams, it provides a free MIT-licensed OSS toolkit with 261 skills and 64 agents, plus a GitHub App for repo-native automation. The system includes three layers: the distribution layer (OSS repo), the protection layer (AgentShield with 102 security rules), and the control-plane layer (ECC 2.0 for observability and cross-harness orchestration). AgentShield scans every agent session, catching config vulnerabilities and enforcing policy. The GitHub App turns repository history into reusable skills and defaults, and can trigger PR reviews via comments like "/ecc-tools analyze". ECC 2.0, shipped stable, offers session visibility, token optimization, and cross-harness operations above the underlying tools. Pricing is freemium: the OSS layer and public-repo GitHub App are free; Pro at $19/seat/month adds private-repo analysis, PR-triggered audits, and AgentShield-backed scanning; Enterprise contacts sales for SSO, custom policies, and dedicated support. While the depth of configuration may overwhelm casual users, ECC uniquely combines security, portability, and automation for teams relying on multiple coding agents.

Behind the Verdict

ECC stands out as the only open-source agent harness that explicitly targets multiple coding agent platforms. Unlike single-harness tools, ECC gives you portable skills and agents that work across Claude Code, Codex, Cursor, and OpenCode. That means you can standardize conventions and security policies even if your team switches agents. The 261 skills and 64 agents are a genuine advantage — you get test-driven development workflows, code reviewer agents, and OWASP Top 10 security checks out of the box. AgentShield is a clever addition, scanning every session for config vulnerabilities. For teams that already use GitHub, the GitHub App integration is seamless: comment "/ecc-tools analyze" on a PR and get a generated pull request with pattern inspection. ECC 2.0 adds a control plane for session visibility and token optimization, which is useful for teams juggling multiple agent sessions. Where it bites: the setup is not trivial. You need to install via npm and configure profiles (core, developer, security, or full). Beginners or solo developers using a single agent may find ECC overkill. Also, support is limited to Discord community for free users; Pro gets priority email. Compared to alternatives like Continue.dev or LangChain, ECC is more focused on agent security and cross-harness portability than on model routing or prompt chaining. If you're a team using multiple coding agents and need governance, ECC is worth the setup. If you're a solo developer on one agent, skip it.
