PreFlight versus Snyk
This is not a substitute-product comparison. Snyk is a developer security platform for code, open-source dependencies, containers, infrastructure, APIs, and web applications. PreFlight is a release-confidence system for the deployed surface, provider handoffs, customer journeys, payments, monitoring, and evidence.

02 / Choose Snyk when
Snyk owns the brief.
Developer and AppSec teams finding and governing risk in code, dependencies, containers, IaC, APIs, and web apps across the SDLC.

Decision lensPreFlightSnykWhat should decide it
Primary object
Live application, provider, deploy, journey, and release evidence.
Code, dependencies, containers, cloud/IaC, APIs, and web applications.
Repository and supply-chain risk points to Snyk; live customer-path proof points to PreFlight.
Workflow position
Before launch, at deploy, and continuously in production.
IDE, Git, CLI, build pipeline, and broader SDLC governance.
Use both when pre-merge prevention and post-deploy verification matter.
Dependency remediation
Can surface dependency and public exposure signals, but is not a full dependency-governance platform.
Dedicated dependency graphs, vulnerability intelligence, policies, and fix guidance.
Snyk is the specialist here.
Browser journeys
Records critical user steps and assertions against a connected environment.
Not the core job described by Snyk's platform positioning.
PreFlight owns the user-journey proof layer.
Payment fulfillment
Traces Stripe checkout through webhook verification to Supabase access.
Not the primary application contract Snyk advertises.
PreFlight is purpose-built for this SaaS-specific contract.
Governance
Release rules, evidence, owners, incidents, reports, and trust surfaces.
Enterprise AppSec policies, risk prioritization, RBAC, audit logs, and cross-SDLC visibility.
Snyk has the deeper AppSec governance scope; PreFlight has the release operations context.
The verdict. No fake winner.
For a serious SaaS, the strongest answer is often Snyk plus PreFlight: prevent known code and supply-chain risk before merge, then verify the deployed customer contract after release. If you can buy only one, choose by the failure you are accountable for—not by which tool has the longer feature list.
