gitlab-harvester 0.1.3

Build a GitLab instance project index and search repositories for sensitive keywords (API-only, no cloning).

GitlabHarvester — Global GitLab Code & Secret Search Tool (Python)

GitlabHarvester is a fast, scalable tool for searching keywords across an entire GitLab instance using the API — without cloning repositories.
Built for security audits, secret discovery, compliance checks, and large‑scale code intelligence across thousands of projects.

Global term search across a full GitLab instance — especially valuable for GitLab CE environments.

---

🚀 Overview

GitLab Community Edition does not provide full instance‑wide code search like EE.
GitlabHarvester fills this gap by:

• building a lightweight instance project index
• scanning repositories via API
• streaming results in JSONL
• supporting resumable sessions
• keeping memory usage constant

Designed to operate efficiently on environments with 10k–100k repositories.

🔍 Key Advantages

Problem	Solution
No global search	Instance‑wide scan
Cloning thousands repos	API‑only scanning
Large instances	Streaming architecture
Repeated audits	Cached project index

---

✨ Features

• Instance‑wide keyword search
• No repository cloning
• JSONL project index
• Branch scanning strategies
• Smart fork analysis
• Resume interrupted scans
• Streaming output
• Low memory footprint
• Automation‑friendly

📦 Installation

Recommended — install from PyPI (isolated environment)

pipx install gitlab-harvester

Run:

gitlab-harvester --help

---

Alternative — pip

pip install gitlab-harvester

---

Development install

git clone https://github.com/Cur1iosity/GitlabHarvester.git
cd GitlabHarvester
pip install .

Editable mode:

pip install -e .

---

Install latest dev version

pipx install git+https://github.com/Cur1iosity/GitlabHarvester.git

---

Requirements

• Python 3.10+
• GitLab token with read_api permission

---

⚡ Quick Start

Search single keyword:

gitlab-harvester -H https://gitlab.example.com -t $TOKEN --search password

Search from file:

gitlab-harvester -H https://gitlab.example.com -t $TOKEN --terms-file words.txt

Build index only:

gitlab-harvester -H https://gitlab.example.com -t $TOKEN --dump-only

---

🌿 Branch Control

Two independent controls:

• --index-branches — stored branches
• --scan-branches — scanned branches

Example:

gitlab-harvester -H ... -t ... --scan-branches 10

Store all + scan all:

gitlab-harvester -H ... -t ... --index-branches all --scan-branches all

Shortcut:

--branches N

---

🍴 Fork Strategies

--forks skip|include|branch-diff|all-branches

Recommended → branch-diff

Behavior:

Mode	Behavior
skip	ignore forks
include	treat as normal repos
branch-diff	scan default + unique branches
all-branches	full exhaustive scan

---

💾 Sessions & Resume

Create session:

gitlab-harvester -H ... -t ... --terms-file words.txt --session audit

Resume:

gitlab-harvester -H ... -t ... --session-file audit.jsonl --resume

---

📊 Output

Two file types:

File	Purpose
Project index	cached project metadata
Session file	hits + checkpoints

Format → JSONL (streaming‑friendly)

---

🧰 Post‑Processing Utilities

Deduplicate results

python scripts/dedup.py --input session.jsonl --output dedup.jsonl

Options:

• --no-normalize
• --sqlite db.sqlite

---

Convert JSONL → JSON

python scripts/convert_jsonl_to_json.py \
  --input session.jsonl \
  --output result.json

Pretty format:

jq . result.json > formatted.json

---
