Upload OpenAPI Specifications or connect the Treblle SDK. Governance checks start immediately against both design-time specs and live production traffic.
Each API receives a score from 0–100 across security, design quality, performance, and AI readiness, mapped to an A–F grade that leadership understands immediately.
Block low-quality APIs from reaching production via CI/CD integration, generate leadership reports, and track scores across versions over time.
What is API Governance?
API governance is the set of policies, standards, and controls an organization applies to ensure its APIs are consistent, secure, and fit for use, from initial design through production operation. Without governance, API quality degrades silently: endpoints ship without documentation, security standards drift between teams, and technical debt compounds across a portfolio of hundreds of services.
Treblle enforces governance automatically at design time, in CI/CD pipelines, and at runtime, scoring every API against design quality, security posture, performance, and AI readiness simultaneously.
Shift Left
Most governance failures are expensive because they're caught in production. Treblle evaluates OpenAPI Specifications before a line of code is deployed: in VS Code as developers design, in native desktop validation apps for architects, and as an automated gate in your CI/CD pipeline. Quality issues get flagged while they're still cheap to fix.
Analyzes OpenAPI Specifications to assess API quality before a single line of code is deployed, catching design issues while they're still cheap to fix.
Gives developers instant governance feedback as they design APIs in their editor, shifting quality left without adding process overhead.
Runs governance checks automatically via the Treblle CLI on every pull request or deployment, blocking low-quality APIs from reaching production.
Runtime Quality
A spec that looks clean can behave badly in production. Treblle evaluates every API against actual request and response data, not just what the spec promises. The API Maturity Score combines design quality, security posture, and runtime performance into one number, and Design-to-Production Drift shows exactly where quality breaks down between spec and live behavior.
Evaluates API quality from actual request and response data in production, measuring what your APIs actually do, not just what the spec promises.
Compares design-time scores against runtime scores to pinpoint exactly where quality degrades between spec and production.
Automatically rates every API from 0–100 across design quality, security posture, performance, and AI readiness, mapped to A–F grades leadership understands immediately.
Custom Standards
Treblle validates against industry best practices by default. Organizations with their own API guidelines can upload rules in Spectral format, the open standard for API linting, and Treblle enforces both sets simultaneously on every API, across every team, without manual review cycles.
Upload your own rules in Spectral format and Treblle enforces your organization's specific API standards alongside built-in checks, on every API, every time.
Native Mac and Windows apps for quick OpenAPI Specification validation, letting architects and tech leads assess API quality without touching a terminal.
Leadership Reporting
Treblle tracks governance scores per API version over time and generates reports formatted for leadership and board presentations. Trends, regressions, and improvements are translated from technical scores into the metrics decision-makers actually use, with no manual data extraction required.
Generate and download governance reports formatted for leadership teams and board presentations, turning technical scores into executive-ready documentation.
Tracks governance scores for each API specification version independently, showing whether your APIs are improving or regressing over time.
Treblle works best when working in unison. Check out other capabilities that will help you make the most out of your API landscape.
API Compliance
Runtime checks for GDPR, PCI-DSS, HIPAA, and CCPA run alongside security scanning, with compliance signals feeding directly into threat context.
API Discovery
Know every API in your inventory before you secure it. Discovery feeds the baseline that shadow API detection measures against.
API Security
Connect governance quality data with real-time threat detection across 100% of your API traffic.
