NucleusSnyk ships your code to the cloud. Nucleus finds exploits locally.
Snyk uploads, pattern-matches, sends back a triage queue. Nucleus catches it inside your IDE — launches hundreds of AI agents in parallel to investigate which actually exploit. Local. Private. Deeper than rule-based scans — a self-improving codebase, not a backlog.
Snyk's queue is every rule-pack hit. Nucleus's queue is every actual exploit — each finding checked for reachability, sink, data flow, auth state.
Find the CVE before it finds you.
Scanners flood you with noise. Nucleus sweeps your repo against thousands of threat signatures, then launches hundreds of AI agents in parallel — each one opens the file, traces the data flow, and tells you what actually exploits. Local. Private. Ranked P0 → P2, patch ready.

5 of 10 findings investigated by the agent — false positives dismissed, real ones prioritized.
SQL injection via string concatenation
src/api/users/[id]/route.ts:42
Description
User-controlled `id` is concatenated directly into a raw SQL query, bypassing parameterization.
Code
const user = await db.query(
`SELECT * FROM users WHERE id = '${req.params.id}'`,
)Remediation
Use parameterized queries (prepared statements) or the ORM query builder. Never interpolate user input into SQL strings.
Same bill. Whole stack.
Who switches, honestly.
Stay on Snyk if you're an AppSec team running a dedicated program, you need deep SCA across a thousand-package transitive tree, you ship to FedRAMP Moderate procurement buyers, or your security questionnaire literally names Snyk.
Switch to Nucleus if
- you want the catch in the editor pre-commit
- you want a multi-stage AI investigation across the whole repo instead of rule-based diff scans
- you don't want your code uploaded to a third-party SaaS backend for review (Nucleus runs locally — no tenant ingestion)
- you'd rather buy the reviewer and the agent on one bill than stack Snyk + an IDE + a reviewer + an asset generator
- or you want 50+ models across 10+ providers powering the review
every new frontier release stays inside the same subscription instead of forcing a vendor switch.
Having the full stack in one place, compounds.
The honest answers.
One bill. Three reasons.
Snyk sells scans. Nucleus is the whole desk.
Snyk Team is $25/dev/mo for SCA + SAST only — and Ignite is ~$105/dev/mo once you want the AI features. To actually ship, you still buy an IDE assistant, a PR reviewer, and an asset generator elsewhere — four bills, four vendors. Nucleus Plus is $20/dev/mo all-in: IDE + reviewer + security investigation + Atlas chat + automations + image/video. And it rides on the Claude or ChatGPT sub you already pay — no model markup, no per-token tax.
Scanners flag patterns. Atlas asks if it exploits.
Snyk's SAST uses DeepCode AI plus rule packs to pattern-match on the AST — but findings still ship without per-environment exploit reasoning, and the queue gets long enough that teams learn to ignore it. Nucleus launches hundreds of AI agents in parallel across the whole repo — each one asks can this be reached, does input flow here, is auth bypassable — so the finding that lands is one you'd actually triage. Local & private: code stays on your machine; only the findings do.
Sentry spikes. Nucleus ships the patch.
A Sentry exception, a secret commit, a Dependabot vuln Friday night — a Nucleus agent spins up, investigates the blast radius, opens the patch PR. Snyk posts to the dashboard; the fix waits in the queue. Nucleus opens the diff you review.
One Subscription. Self Improving Codebase.
