Tuvio vs Snyk: A Snyk Alternative for Apps Your AI Assistant Wrote

Snyk is a security platform built for development teams: checks in the editor, on every pull request and in CI, across code, dependencies, containers and infrastructure. Tuvio is built for one person shipping an app an AI assistant wrote: paste the repository or the site address, and get a plain-language launch report on the problems these apps tend to have, such as open Supabase tables, keys in git history and a Stripe webhook nobody verifies.

If you are searching for a Snyk alternative, that difference matters more than any feature list. This post sets the two side by side, says plainly when Snyk is the better choice, and when Tuvio fits better.

Who each one is for

Snyk's own pages aim it at developers and teams. Its Free plan is "for individual developers and small teams looking to stay secure as they build", its Team plan "for development teams of up to 10 developers", and the platform as a whole at "AI-building teams" and security teams. It lives where developers already work: an IDE plugin, the command line, CI pipelines and pull-request checks, with one dashboard on top.

Tuvio is for someone who built an app with Claude Code, Cursor, Codex or Lovable and wants to know, before launch, whether it is safe to put in front of users. There is nothing to install and no pipeline to configure. You paste a repository or a site address and read a report written for someone who did not write the code by hand. A fix arrives as a prompt to paste into the assistant that wrote the code.

Side by side

AI reviews outside Pro cost $1.99 for one or $4.99 for three. Tuvio's scans themselves are free on both plans.

What it takes to start, and to rescan

Snyk. Per Snyk's getting started docs, you create an account, then connect your code: "To scan your code, you must first integrate Snyk with the repository holding that code", through a source control integration or the CLI on your machine. Then you import a project, which runs the first scan and schedules regular scans and pull-request tests. The editor plugin and CI checks are set up separately.

A Snyk test is also not the same thing as one scan of your app. Per Snyk's docs on what counts as a test, dependency scanning counts the manifest files where it finds vulnerabilities ("one repository can have many manifest files", and "each manifest file in scope will generate a distinct test"), infrastructure scanning counts one test per Terraform or other IaC file, container scanning one per Dockerfile or image, and Snyk Code one per repository scanned. Tests are triggered by pull requests, by pushes from your source control, by a retest from the web UI, and by CLI and API calls. An app with separate package.json files for its frontend and backend can use two dependency tests in a single scan. On the Free plan, tests on private repositories come out of the allowances below.

Tuvio. Paste the repository or site address on the scan page. Nothing to connect for a public repository, nothing to install. One scan covers the whole repository, every check, however many package.json files it has. A rescan is one button on the project page, or one sentence to your AI coding tool, and it isn't counted against a monthly number.

Is Snyk free?

Yes, with limits. Snyk's Free plan costs $0 a month. The catches, from Snyk's own pages:

• Test limits on private repositories, and reruns count. Per Snyk's plans page, the free allowances are 100 Snyk Code tests a month, and 200 Open Source, 300 infrastructure and 100 container tests. Snyk's docs on what counts as a test say these limits apply to private repositories only, so if your app's repository is private, they apply to you.
• 5 projects.
• AI fixes for a limited time. The Snyk Code page lists Snyk Agent Fix on Free "(limited time only)", with no end date.
• How often projects are retested is not yours to set. Configuring daily or weekly retests "is in Early Access and available only with Enterprise plans", per Snyk's monitoring docs.
• An idle account is removed. A Free account with no activity for more than 60 days is "slated for deletion", per Snyk's plan docs.

Where Tuvio's free plan goes further

For one person checking one AI-built app, these are the differences that count:

• No monthly test allowance. A free account scans up to 5 repositories, public or private, and rescans each one once a day when it has new commits. Scans are not counted against a monthly number.
• No account for the first look. The first scan of a repository needs no account, and the live-site scan is free with or without one.
• Checks written for how these apps break. Supabase row level security in your migrations, Stripe webhooks, AI SDK keys in the browser, keys anywhere in the git history, with a launch verdict in plain language.
• Your AI coding tool can use it. A free account works from Claude Code, Cursor or Codex: "Scan this repo with Tuvio".

Tuvio's free plan has limits too

• 5 repositories, and one rescan a day per repository, only when there are new commits.
• One free AI review. Fix prompts come from an AI review, so after the first one they cost $1.99 for one review or $4.99 for three.
• No monitoring: the weekly rescan and its emails are on Pro.
• No pull-request, IDE or CI checks, on any plan.

When Snyk is the better choice

Snyk is the stronger pick in several situations, and it is worth being clear about them.

• You work as a team and want every pull request checked. Snyk's pull-request checks scan code and dependencies before a merge. Tuvio does not sit in your pull requests or your CI.
• You want findings while you type. Snyk's IDE plugins scan in the editor. Tuvio scans what is pushed to the repository.
• You ship container images. Snyk Container scans images. Tuvio checks the Dockerfile's settings, not the vulnerabilities inside a base image.
• You need license compliance. Snyk checks open-source licenses on pull requests. Tuvio checks dependencies for known vulnerabilities only.
• You need to test a running app and its API dynamically. Snyk API & Web is a DAST product. Tuvio's site scan reads what a site serves to anyone; it never signs in or tries to break anything.
• You have a security team, CI gates and compliance reports to produce. That is the job Snyk's Team and Enterprise plans are built for.

When Tuvio fits better

• You built the app with an AI assistant and you are the only one shipping it. Tuvio's report is written for that reader: a launch verdict, findings in plain language, and a fix prompt for the assistant that wrote the code.
• Your app runs on Supabase. Tuvio flags the row level security shapes that leak data in SQL migrations: policies open to anyone, policies open to any logged-in user, migrations that turn RLS off (not yet tables that never had it on), policies that trust user_metadata, and security definer functions without a search_path. If that list reads like a foreign language, Supabase RLS disabled in public explains it.
• You take payments or call an AI model from the app. Tuvio flags a Stripe webhook that skips its signature check or keeps going when the check fails, a checkout amount taken from the request, and an AI SDK running in the browser with its key in a public variable.
• You might have committed a key months ago. The secret scan reads the git history, not only today's files, and the report says how far back it read.
• You want to check the live site too. The site scan is free and needs no account.
• You don't want to set anything up. No plugin, no CLI, no pipeline. Your AI coding tool can also ask Tuvio directly: "Scan this repo with Tuvio".

What Tuvio checks, stack by stack, and what it doesn't, is on the coverage page.

Using both

They don't conflict. A sensible split for a solo builder: Snyk's Free plan in your editor while you work, and a Tuvio scan of the repository and the live site before you launch and after big changes. If your code is on GitHub, turn on Dependabot as well; it is free on every plan and opens pull requests for vulnerable packages. How to fix npm vulnerabilities covers what to do when the alerts arrive.

The quickest way to see which fits is to try it: scan your repository or your live site for free. The first scan needs no account, and the report shows what Tuvio flags in your app.
