quodeq

AI-powered code quality and security scanner

v1.3.0

Watch the 2-min demo · Website · Blog · Releases

AI models can now autonomously find and exploit zero-day vulnerabilities across operating systems, browsers, and web applications. Thousands of previously unknown flaws uncovered in weeks, not years.

The code you ship today will be read by models that can spot what humans miss. But the tools to prepare for this are locked behind enterprise contracts and partner programs.

Quodeq exists to change that.

Open source. MIT license. Runs locally. No telemetry. No account. No servers.

Scans any codebase with AI across six quality dimensions from ISO 25010: Security, Reliability, Maintainability, Performance, Flexibility, and Usability.

Every finding maps to a CWE identifier. You get grades, violations with line numbers, and a fix plan. Cloud providers (Claude, Gemini, Codex) for speed. Local models via Ollama for privacy.

What It Finds

CRITICAL    src/db.py:15        SQL injection via string concatenation     CWE-89
            query = f"SELECT * FROM users WHERE id = {user_id}"

MAJOR       src/auth.py:42      Hardcoded credentials in source code       CWE-798
            credentials = {"user": "admin", "pass": "secret123"}

MINOR       src/utils.py:23     Bare except clause hides errors            CWE-396
            except: pass

COMPLIANT   src/api.py:88       Parameterized query prevents injection     CWE-89
            cursor.execute("SELECT * FROM users WHERE id = ?", (user_id,))

Each finding includes a reason, the offending code, and a fix plan. Results are stored as JSON on your machine.

Getting Started

1. Prerequisites

Debian/Ubuntu heads-up: If you use the native desktop window (not --browser), you'll need sudo apt install -y python3-gi gir1.2-webkit2-4.1 too. Otherwise quodeq will auto-fall-back to opening the dashboard in your default browser.

Windows note: The test suite runs on windows-latest as a blocking CI gate, so a Windows regression blocks the PR. The desktop window (WebView2) is smoke-tested manually per release. If anything misbehaves, please open an issue.

Minimum versions: Python 3.12+. (The dashboard UI ships pre-built inside the wheel, so end users no longer need Node.js or npm. Contributors who want to iterate on the UI source need Node 20+ and npm 10+, see CONTRIBUTING.md.)

2. Install quodeq

pipx install quodeq    # isolated, recommended
# or: pip install quodeq

3. Pick an AI provider

Quodeq needs an LLM to do the evaluation. You have two options:

Local, free, private — Ollama with Gemma 4:

# install ollama from https://ollama.com/download, then:
ollama pull gemma4:26b
ollama serve    # runs in the background

Cloud, faster — one of the agentic CLIs (at least one):

• Claude Code — npm install -g @anthropic-ai/claude-code
• Codex CLI — npm install -g @openai/codex
• Gemini CLI — npm install -g @anthropic-ai/gemini-cli

4. Launch the dashboard

quodeq

The dashboard opens at http://127.0.0.1:7863. Use Settings → AI Provider to select the one you installed in step 3, then Evaluate to point at a project and start your first scan.

If the native window doesn't show up (common on Linux without GTK), run quodeq --browser instead.

macOS App (beta)

Download the .dmg from Releases, open it, and drag Quodeq.app to Applications. On first launch:

xattr -cr /Applications/Quodeq.app    # Required for unsigned apps

Or right-click the app, select Open, then click Open in the dialog.

Dashboard

• Grades and scores per dimension with A-F letter grades, numeric scores, and trends across runs
• Violations explorer to drill into findings by file, principle, or CWE classification
• Code map showing a visual heatmap of where issues concentrate in your codebase
• Custom standards to create your own evaluation dimensions or import from the library

Click any dimension, file, or principle to explore the details. Dismiss false positives directly from the UI.

Running quodeq is equivalent to quodeq dashboard. Both open the same UI.

CLI

quodeq evaluate /path/to/project
quodeq evaluate /path/to/project --scope src/api    # Scoped to a subdirectory
quodeq evaluate /path/to/project -d security        # Single dimension

AI Providers

Choose what fits your workflow. Configure in Settings from the dashboard.

For local analysis we recommend Gemma 4 (gemma4:26b). Reducing the context window to 32k still gives good results and allows running multiple subagents in parallel.

Using llama.cpp

llama.cpp is one process per model, fixed at launch. Start llama-server yourself, then point Quodeq at it from Settings → AI Provider → llama.cpp.

# Quodeq creates ~/.quodeq/logs/ on first launch — just redirect there
# and the CONSOLE button picks it up automatically.
llama-server -m path/to/target.gguf --port 8080 \
  > ~/.quodeq/logs/llama-server.log 2>&1

# Speculative decoding (MTP), pair a target with a smaller drafter
llama-server -m path/to/target.gguf -md path/to/drafter.gguf --port 8080 \
  > ~/.quodeq/logs/llama-server.log 2>&1

Quodeq probes http://localhost:8080 and looks for the log file at ~/.quodeq/logs/llama-server.log (or platform-standard locations like ~/Library/Logs/llama-server.log on macOS). Override with LLAMACPP_LOG_FILE. To use a different port or host, set LLAMACPP_BASE_URL. To switch models, stop llama-server and relaunch with a different -m.

How It Works

1. Detect languages, frameworks, and project structure
2. Analyze with AI agents that read the code using read-only tools
3. Collect findings as structured JSONL via tool calls
4. Score against ISO 25010 principles with CWE classifications
5. Report per-dimension grades, violations, compliance, and fix plans

Results are stored in ~/.quodeq/evaluations/ and persist across sessions. Works with any language. The AI analysis engine reads and understands code regardless of the tech stack.

Quodeq scores each principle on a 0 to 10 scale using four independent constraints. Full details in the scoring formula documentation.

Standards

By default, Quodeq evaluates the six ISO 25010 dimensions. It also ships with Clean Architecture and Domain-Driven Design standards. You can create your own from the dashboard, or ask any AI to generate one as a .json file and import it.

Development

Run from a fresh checkout:

git clone https://github.com/quodeq/quodeq.git && cd quodeq
uv sync                   # install Python deps into .venv/
uv run quodeq             # launch the dashboard
uv run pytest             # run the test suite

Same OS prerequisites as the pipx install (Python 3.12+), plus Node 20+ and npm 10+ because a source checkout builds the dashboard UI from the working copy. You also need a configured LLM provider (Ollama or Claude Code / Codex CLI / Gemini CLI) before you can actually scan anything.

If the dashboard window doesn't appear on Linux, run uv run quodeq --browser (the native window needs python3-gi + gir1.2-webkit2-4.1, which aren't pulled in by the pip wheel).
