The record

Purpose: SpecDoc manages OpenAPI specs as code, enforces governance policies in CI/CD, and publishes developer portals.
Version registry: Each successful pipeline publish creates an immutable, sequentially numbered version of an OpenAPI spec.
Breaking-change detection: SpecDoc compares each new version with the previous one and classifies changes as breaking or non-breaking.
Governance: Built-in governance policies include off, standard, and strict modes, and teams can define custom rules in a repository YAML file.
Developer portals: Portals provide an interactive API explorer, versioned docs, OpenAPI export, generated cURL, JavaScript, Python, and Go snippets, and search.
Portal access: Portals can be private, protected, or public, and the interactive explorer sends requests directly from the customer’s browser to the API server.
CI/CD integrations: The docs provide pipeline examples for GitHub Actions, Azure DevOps, GitLab CI, Jenkins, CircleCI, and Bitbucket Pipelines.
CLI requirements: The CLI can run through npx or be installed globally, and the docs state that Node.js 18+ is available on major hosted CI runners.
Security and storage: The privacy policy says data is stored in EU-West by default, encrypted in transit with TLS 1.2+ and at rest with AES-256, and production access is protected by MFA.
Privacy: The privacy policy says SpecLayer does not sell personal data and that spec content sent to Anthropic for AI Enrichment is not used to train AI models.
Retention: The privacy policy says Free plan spec versions and governance results are retained for 90 days, while Pro and Enterprise retention is unlimited.
Plan limits: The pricing page says viewer and billing roles are free, and exceeding plan limits triggers notice and time to upgrade before access is cut off.
Other product: KlusterAlert is described as a Kubernetes monitoring product with automatic issue detection and alerts through Teams, Slack, or email.
Price from: $29/mo
