Free Snyk Alternative for Indie Devs: Trust vs Snyk vs Gitleaks
An honest comparison of Trust, Snyk, and Gitleaks for solo and vibe-coder devs. Free tiers, no-signup scans, DAST plus SAST plus secrets plus SCA, and when NOT to pick Trust.
· 7 min read
If you shipped an app with Cursor, Lovable, or v0 last weekend and then searched "snyk alternative free" or "free github security scanner," you already know the problem: enterprise security tools are built for teams with a budget, and the truly free tools each only cover one slice of the picture. This is an honest look at three options — Trust, Snyk, and Gitleaks — so you can pick the right one instead of the loudest one.
Short version: all three are good tools, they just aim at different people. Trust is built for indie and vibe-coder devs who want one free pass over both a live site and a repo with no account. Snyk is a deep, enterprise-grade dependency and code platform. Gitleaks is the best free open-source secret scanner, and nothing more. Let's be specific.
What each tool actually does
The honest capability breakdown matters more than marketing, so here it is across the eight things indie devs care about: live-URL DAST, repo SAST, secret detection, dependency and SCA scanning, a genuine free tier, no-signup scanning, MCP or IDE integration, and AI fixes.
Trust
Trust scans two things in one pass. Point it at a live URL and it runs DAST against the running site using Nuclei (10k+ templates) to catch misconfigurations, XSS, and exposed files like a public .env. Point it at a GitHub repo and it does secret detection (around 22 secret types), SAST for code-level flaws, and dependency and SCA checks via OSV. Findings come with AI-powered fix suggestions, and it plugs into your editor through MCP for Cursor and Claude Code.
- Live-URL DAST: yes — this is the piece Snyk gates and Gitleaks simply does not do.
- Repo SAST, secrets, and dependency/SCA: yes, all in the same repo scan.
- Free tier and no-signup: yes — you can run a URL scan with no account at all; a Pro plan adds more for heavier use.
- MCP/IDE and AI fixes: yes — MCP in your IDE plus AI-generated remediation.
Snyk
Snyk is the heavyweight, and it earns the reputation. Its platform spans Snyk Open Source (SCA), Snyk Code (SAST across 19+ languages, powered by DeepCode AI), Snyk Container, Snyk IaC, and Snyk API & Web (its GenAI-powered DAST). The Snyk Vulnerability Database is genuinely excellent, and it has mature IDE plugins for VS Code, IntelliJ, and Eclipse, automated fix pull requests on paid plans, and an MCP server of its own for AI assistants.
- Deep SCA and CVE coverage: best-in-class, and the main reason to choose it.
- SAST, container, IaC, DAST: all present, but DAST (Snyk API & Web) is a paid product, not part of the free tier.
- Free tier: real but limited — roughly 200 open-source (SCA) tests, 100 container tests, and 300 IaC tests per month. Public open-source projects get unlimited tests. No credit card required, but you do need an account.
- No-signup: no. You sign up and connect a repo before anything runs.
Gitleaks
Gitleaks is the community favorite for one job: finding hardcoded secrets. It is MIT-licensed, free forever, a single fast binary, and it scans full git history, uncommitted diffs, files, and stdin. It shines as a pre-commit hook and in CI (there is an official GitHub Action, plus SARIF output for code scanning). But it is deliberately narrow — secrets only. No SAST, no dependency or SCA analysis, no live-site DAST, no hosted UI, and no AI fixes. It is a CLI/CI tool, so you run it yourself.
- Secret detection: excellent, and free with no strings — the whole point.
- Everything else (DAST, SAST, SCA): not offered. That is by design, not a gap to complain about.
- Free and no-signup: yes on both — it is open source and runs locally.
- IDE/AI: no MCP or AI fixes; it is a CLI-and-CI tool.
The one-line summary
See what your live site and repo actually expose
Paste a URL or connect a GitHub repo. Free, no signup, results in about a minute.
Run a free scan →Where Trust wins for indie and vibe-coder devs
The wedge is coverage per unit of effort. As a solo dev, you do not want to stitch together a secret scanner, an SCA tool, a SAST tool, and a separate DAST product — each with its own config and account. Trust's advantage is that one scan touches your running site and your repo, and the live-URL DAST catches the class of bugs that source-only tools structurally cannot see: a misconfigured header, a debug endpoint left open, or a .env that is publicly reachable in production.
- No signup to start. Paste a URL and go — useful when you just want a gut check before a launch.
- DAST plus SAST plus secrets plus SCA in one pass, instead of four tools.
- MCP in your IDE. Ask Cursor or Claude Code to scan and fix without leaving the editor. See the MCP setup.
- AI fix suggestions written for the exact finding, so "what do I even do about this" is answered inline.
If you built with AI, this combination matters more than usual — AI-generated apps skew toward exactly these mistakes. More on that in is your AI-generated app secure?
When NOT to pick Trust
An honest comparison has to say where the other tools are the better call. There are real cases where Trust is not what you want:
- You need the deepest possible dependency and CVE coverage. If your product lives or dies on catching every last vulnerable transitive package — or you have compliance, enterprise reporting, and per-developer governance needs — Snyk's vulnerability database and SCA depth are hard to beat. Pay for Snyk.
- You just want a free pre-commit or CI secret hook. If all you need is to block a commit that contains an API key, Gitleaks is perfect: MIT-licensed, self-hosted, runs in under a second on a diff, and never phones home. Use Gitleaks.
- You want IDE plugins for IntelliJ or Eclipse specifically, or automated fix PRs wired into your git provider today — Snyk's ecosystem is more mature there.
Plenty of teams run more than one. A common setup: Gitleaks as a free pre-commit hook, Trust for fast full-stack scans of the live site and repo, and Snyk once dependency depth or compliance becomes the priority.
Bottom line
If you are a solo or vibe-coder dev who wants the widest real coverage for zero dollars and zero setup, Trust is the strongest free Snyk alternative — because it is the only one of the three that scans your live site and your repo for DAST, SAST, secrets, and SCA in a single no-signup pass, with AI fixes and MCP in your editor. Reach for Snyk when you need enterprise dependency depth, and Gitleaks when you want a free secret hook. Then run a scan and see what is actually exposed.
