Zoo Code positions itself as a community-maintained continuation of Roo Code after the original product shutdown. That lineage helps former users migrate, but it is not proof that every setting, safety default or commercial service is identical.
What the evidence actually establishes
The project’s own site describes Architect, Code and Debug modes, model-provider flexibility, diff review, customizable workflows and optional external tools through MCP. Its GitHub repository describes a migration path and independently maintained releases. Similar configuration formats can lower switching cost; code custody, extension signing and cloud billing still change when the publisher changes. Even where settings transfer, providers may use different prompts, local storage and network endpoints.
How a development team should use or migrate it
Treat a Roo-to-Zoo migration as a controlled software upgrade. Back up rules and snippets, use the publisher’s documented migration guide, and install the successor only from its official distribution links. In a sample repository, inspect the new extension ID, account sign-in, provider key storage, tool approval dialogs and the format of exported configuration. Then run a plan-only architecture task followed by a tiny test-file change. Verify that diff review occurs before acceptance where configured, and inspect whether MCP tools can read or write resources outside the repository.
A realistic engineering example
Imagine a maintainer whose workflow depends on a custom Architect mode that can draft a refactoring plan without touching files. In a fork migration, import that mode and explicitly inspect whether its tool access remains read-only; names alone do not prove identical semantics. Next configure a Code mode with filesystem edits allowed but shell commands requiring explicit confirmation. Submit a trivial failing unit test and verify the extension produces a readable diff, reports proposed commands and respects stop requests. Finally inspect its gateway and model-provider settings to ensure account credentials are stored where expected. The same UI and similar source lineage should lower migration effort, not replace a security review.
Security, licensing and production limits
The vendor site also mentions optional gateway or cloud-agent offerings; their privacy, credit and deployment terms are not inherited from open-source licensing. Apache-2.0 code availability does not mean every hosted service is free or governed by the same data-handling policy. The long-term maintenance and security-response capacity of a community fork should be measured through releases, vulnerability disclosures and contribution review, not just star counts or a familiar interface.
Who should choose it and what to compare
Zoo Code is a logical continuity option for a team that invested heavily in Roo-specific modes and is willing to evaluate a new maintainer. Compare with Cline and Continue using a private pilot repo, not a production database. Favor the project whose permission model and exportability best match team policy.
Decision checklist
- What is the exact successor extension publisher?
- Are provider keys imported or entered again?
- Do tool approvals behave the same as before?
- Which hosted services have separate terms from the source license?
