ESLint
Editor pickCustom rule authoring with shared rule utilities and AST node visitors for project-specific correctness checks.
Best for: Fits when teams need enforceable JavaScript and TypeScript code-quality checks in CI with fast iteration cycles.

Comparison Table
Semgrep
API-firstRule-driven static analysis tool for code security and quality checks with fast developer feedback.
Custom rule queries that combine AST pattern matching with path-sensitive taint reasoning for security-specific detections.
Semgrep evaluates code paths using static analysis that combines AST matching with control-flow and data-flow concepts, which enables targeted security findings rather than only string-based checks. The rule ecosystem covers common application weaknesses, and rule outputs include severity metadata that can drive break-the-build policies in pipelines. Findings are exportable in SARIF, which supports downstream triage in security tools that already ingest SARIF artifacts.
A key tradeoff is that high recall rules can increase false positives unless suppressions and baseline scans are used to manage existing findings. Semgrep fits teams that want fast iteration on custom rules inside CI pipelines, especially when multiple languages and repositories need consistent security checks.
- +Custom rule authoring with a query language that targets specific code patterns
- +SARIF output for CI artifacts that feed existing review and reporting workflows
- +Baseline scanning supports incremental adoption without breaking existing pipelines
- +Built-in suppression mechanisms to reduce repeated false positives
- –Rule tuning is often required to keep high-recall checks actionable
- –Cross-repository governance needs disciplined rule and suppression management

API-firstPluggable JavaScript and TypeScript linting utility with extensive rule ecosystem.
Custom rule authoring with shared rule utilities and AST node visitors for project-specific correctness checks.
ESLint targets JavaScript and TypeScript style and correctness using a configurable rule engine that runs over the abstract syntax tree.
It supports shareable configurations, per-path overrides, and severity tuning to align checks with repository conventions.

Reporting can be routed into common build systems through configured output formatters and SARIF generation tooling.
- +Rule configuration is granular by file, severity, and overrides
- +Auto-fix covers many formatting and safe correctness violations
- +Plugin and parser support extends lint coverage for custom language features
- +CI integration makes break-the-build enforcement straightforward

How to Choose the Right Static Testing Software
Different static testing options mainly separate by how they reduce noise and fit your development workflow. The biggest day-to-day differences show up in how well Update frequency keeps findings current and how well Triage workflow turns results into decisions.
Update frequency controls result freshness
Why it matters
Update frequency controls result freshness, so rules and issue logic don’t lag behind your language versions. When it lags, you spend time chasing old patterns instead of current defects.
How to check
Open the vendor release notes and check how often they ship rule or engine updates. In a demo, switch a sample project to the newest language/runtime you use and confirm results change for current constructs.
False positive handling reduces developer noise
Why it matters
False positive handling reduces developer noise, which determines whether people actually act on findings. If noise stays high, triage turns into ignoring everything.
How to check
Load a sample with known benign patterns and look for consistent classification rather than random swings. Ask how the tool supports clearing or documenting specific findings without breaking the rule set.
Triage workflow maps issues to owners
Why it matters
A good triage workflow maps issues to owners so defects move to fix, not just into reports. It also matters when multiple teams share repositories.
How to check
In the UI, filter by repository, branch, and component, then show how you assign responsibility. Export one finding and confirm it carries enough context (file, location, explanation, history) for a reassignment conversation.
Automation and API surface for batch use
Why it matters
Automation and API surface helps teams run static testing consistently across repos and time windows. It also affects how you govern what runs, when, and with which configuration.
How to check
Request an API example (or automation endpoint) that can trigger a scan and retrieve results. In a demo, show running against a sample batch of projects and pulling back results without clicking through the UI.
Configuration and provisioning for standardization
Why it matters
Configuration and provisioning determine whether teams can reproduce the same findings over time. Without standardized configuration, results drift and comparisons become meaningless.
How to check
Ask how you define rule sets, language versions, and project settings, then show whether they can be applied to new repos. In the demo, create a configuration once and apply it to a second sample project to see if behavior matches.
Audit log and reporting for traceability
Why it matters
Audit log and reporting for traceability lets you answer who changed what and why results shifted. That reduces blame debates during code reviews and compliance check cycles.
How to check
Look for an audit trail for configuration changes and issue state changes (assigned, resolved, suppressed, reopened). Export a report for a sample run and confirm it includes timestamps and the identity of the actor where applicable.
Red flags
- Updates and rule logic appear infrequent relative to your languages.
- Same sample code produces inconsistent classifications across runs.
- Triage relies on manual narration without owner assignment or context preservation.
Fit by situation
- If we ship often with multiple branches, prioritize Triage workflow so findings move to owners reliably.
- If our codebase mixes newer and older language features, prioritize Update frequency to keep rules aligned.
- If teams need repeatable runs and traceability across repos, prioritize Audit log and reporting for traceability.
