What is cloud (SaaS) deployment?

SaaS is the most common deployment model: nothing to run, updates arrive continuously, and nobody on your team has to operate the scanner. For teams without a hard rule on where source code can go, it is usually the lowest-effort option.

The trade-off is that source code is sent to and processed by a third party, which is the main question in regulated environments, and a vendor outage can hold up merges if its check is required. Where SaaS passes a security review, it is usually on the strength of data-residency guarantees and a training-exclusion commitment, not the vendor's security posture alone.

What to look for

Data residency options if you have jurisdictional requirements
Uptime SLA, and whether an outage blocks your merges
What is retained after analysis, and for how long
Certifications backing the vendor's own security claims

Best 20 code quality, security and code review tools offered as a cloud (SaaS) service

Every tool in the directory whose documentation covers this. Shown in a random order that changes on every visit, so no tool gets an advantage from its position.

Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.
