checkmate5 1.3.1

A meta-code checker written in Python.

Betterscan: The Open DevSecOps Orchestration Toolchain

Betterscan (Self hosted and SaaS platform with CLI and Web based interface) used checkmate5 to orchestrate, unify and de-duplicate SAST and scanning tools.

Checkmate5

Python-based meta static-analysis runner that orchestrates multiple language analyzers (Bandit, tfsec, Brakeman, Kubescape, OpenGrep, Staticcheck, etc.) and stores findings in a database backend.

About

Checkmate5 is a cross-language (meta-)tool for static code analysis, written in Python. It orchestrates multiple scanners, normalizes findings into a single view, and de-duplicates overlapping results. This provides a global overview of code quality and security findings across a project—aiming to present clear, actionable insights.

Snapshots let you view findings at a specific point in time, while the issues view can also show the full history of findings across all scans for a project.

Requirements

• Python 3.8+
• Python dependencies (typical): blitzdb5, pyyaml, sqlalchemy, requests
• OpenGrep CLI (local binary) for OpenGrep-based analyzers

Tools used

Checkmate5 orchestrates external tools. Availability, licensing, and usage terms are governed by each upstream project.

• OpenGrep
• Bandit
• Brakeman
• tfsec
• Kubescape
• Staticcheck

OpenGrep setup

Checkmate5 uses the local OpenGrep CLI for opengrep (generic).

Install OpenGrep (recommended):

curl -fsSL https://raw.githubusercontent.com/opengrep/opengrep/main/install.sh | bash

The CLI is expected at ~/.opengrep/cli/latest/opengrep or via OPENGREP_BIN.

It will be instaled when missing.

Rules

Rules are downloaded automatically from:

• https://github.com/opengrep/opengrep-rules
• https://github.com/AikidoSec/opengrep-rules
• https://github.com/amplify-security/opengrep-rules

If rules download fails, OpenGrep falls back to built-in packs.

Config overrides

• CHECKMATE_OPENGREP_CONFIG

Debugging tool output

Run:

checkmate analyze --debug-tools

This prints the OpenGrep command, config paths, and raw JSON results.

Issues output formats

Generate reports from the latest snapshot:

checkmate issues --html-output
checkmate issues --json-output
checkmate issues --sarif-output

Legacy aliases still work:

checkmate issues html
checkmate issues json
checkmate issues sarif

CLI usage

Common flows:

checkmate init
checkmate analyze
checkmate issues

If you use the git plugin:

checkmate git init
checkmate analyze
checkmate issues

List snapshots and filter issues to a specific snapshot:

checkmate snapshots
checkmate issues --snapshot <snapshot_id_or_prefix>

checkmate init examples

Default (SQLite in .checkmate/database.db):

checkmate init

PostgreSQL:

checkmate init --backend sql --connection-string "postgresql+psycopg2://user:password@localhost:5432/checkmate"

MySQL:

checkmate init --backend sql --connection-string "mysql+pymysql://user:password@localhost:3306/checkmate"

Custom SQLite path:

checkmate init --backend sqlite --connection-string "sqlite:////absolute/path/to/my-checkmate.db"

Backend configuration

Projects are configured in .checkmate/config.json. A typical sqlite setup looks like:

{
  "project_id": "YOUR_PROJECT_ID",
  "project_class": "Project",
  "backend": {
    "driver": "sqlite",
    "connection_string": "sqlite:////absolute/path/to/.checkmate/database.db"
  }
}

PostgreSQL example:

{
  "project_id": "YOUR_PROJECT_ID",
  "project_class": "Project",
  "backend": {
    "driver": "sql",
    "connection_string": "postgresql+psycopg2://user:password@localhost:5432/checkmate"
  }
}

MySQL example:

{
  "project_id": "YOUR_PROJECT_ID",
  "project_class": "Project",
  "backend": {
    "driver": "sql",
    "connection_string": "mysql+pymysql://user:password@localhost:3306/checkmate"
  }
}

Notes:

• For PostgreSQL, install psycopg2 (or psycopg).
• For MySQL, install pymysql.
• For SQLite, the file will be created if it does not exist.
