Amimica
Amimica is a free, offline repository scanner for repeated code.
What Amimica is
Amimica is a free, offline repository scanner for repeated code. It detects exact copies, renamed fragments, near-duplicates and recurring patterns, using a deterministic hybrid approach. You can run it as a standalone command-line tool or as an MCP server for Claude Code, VS Code and other compatible editors over stdio. The CLI prints text or JSON, can write results to a file, and provides thresholds for clone score and size, normalization, test exclusion, caching and deeper analysis. Project or global YAML files hold configuration, with environment variables able to override settings. MCP tools scan repositories, list findings, explain matches and compare source regions. Scan results remain in memory during the MCP session and disappear when the server stops. Supported languages listed in the README are Go, JavaScript, TypeScript, Ruby, Objective-C and C#. The MIT-licensed project requires Go 1.25 or later when building from source. Its findings are intended as evidence for human refactoring decisions.
Good
- Free MIT-licensed project
- Deterministic offline scanning
- Detects several clone types
- Text and JSON output options
- MCP tools for explanations and comparisons
Watch out
- Building requires Go 1.25 or later
- No listed CI integration
- No listed IDE integration
- MCP results disappear when the server stops
Who it suits
It suits developers reviewing repositories for duplicate or structurally similar code. It is useful for users comfortable with command-line tools, MCP clients and building from source.
Verdict
Amimica provides configurable, local clone detection through a CLI and MCP server. Its source-build workflow and session-only MCP results are important considerations for adoption.
