Paragon Expands: Full Testing Suite & Production Monitoring

Today we're releasing two major additions to the Paragon platform: a comprehensive testing suite and production monitoring. These features transform Paragon from a code review tool into a complete quality assurance platform that covers your entire development lifecycle.

Beyond Code Review

When we launched Paragon, we focused on one thing: finding bugs before they ship. Code review catches issues at commit time, but modern software teams need coverage across the entire pipeline. What happens after code passes review? How do you know your production services are healthy? How do you ensure critical user flows still work after deployment?

These questions led us to build two new capabilities: a full testing suite that validates your application works as expected, and production monitoring that catches issues before your users do.

Full Testing Suite

Paragon's testing suite supports E2E, integration, unit, and performance testing—all generated from natural language descriptions. Instead of writing test code manually, describe what you want to test and Paragon handles the rest.

The system generates Playwright tests for E2E scenarios, supports multiple testing frameworks for unit and integration tests (Jest, Vitest, pytest, Go test, and more), and runs tests across Chrome, Firefox, Safari, and mobile browsers simultaneously.

Natural Language Test Generation

Describe your test in plain English: "Test that a user can sign up, receive a confirmation email, and log in successfully." Paragon interprets your description, generates the appropriate test code, and executes it against your local environment.

Tests run on your actual machine with your real environment variables, local services, and configurations. No artificial test environments that differ from production.

Performance Budgets

Set thresholds for Core Web Vitals: First Contentful Paint (FCP), Largest Contentful Paint (LCP), Time to Interactive (TTI), Cumulative Layout Shift (CLS), Total Blocking Time (TBT), and Time to First Byte (TTFB). Tests fail when performance degrades below your defined budgets.

Evolving Tests

As your codebase changes, tests can become stale or break. Paragon's evolving tests feature uses AI to analyze code changes and propose test updates. You receive proposals for new tests to add, existing tests to modify, and obsolete tests to remove—each with confidence scores and clear reasoning.

PR Integration

Tests run automatically on pull request creation and push events. Configure which test types run on each trigger, select target browsers, and set up flexible scheduling with custom cron expressions. Results appear directly in your PR comments.

Production Monitoring

Code that passes tests can still fail in production. Network issues, third-party service outages, configuration drift, and dependency vulnerabilities all threaten production stability. Paragon's monitoring features catch these issues proactively.

URL Health Monitoring

Track uptime and response time for any HTTP endpoint. Configure check intervals as frequently as every 10 seconds, with automatic status tracking (up/down/unknown) and latency metrics in milliseconds. Alerts fire only on status changes—when a service goes down or recovers—so you're not spammed with redundant notifications.

Dependency Scanning

Paragon scans your repositories for security vulnerabilities using AI-powered analysis. The scanner detects CVEs from package managers (npm audit, pip, etc.), outdated packages with available updates, deprecated dependencies, license compliance issues (GPL, AGPL, unknown licenses), and unmaintained packages with no updates in over two years.

Each finding is classified by severity—critical, high, medium, or low—with clear remediation steps. Scans run on configurable schedules: hourly, daily, or weekly.

Infrastructure Scanning

Beyond dependencies, Paragon offers infrastructure scanning templates for common security and operational concerns: AWS security misconfigurations, exposed S3 buckets, cost optimization opportunities, Terraform drift detection, and general code quality checks.

Create custom scanning templates or use our pre-built options. Each scan produces structured findings with severity levels, affected resources, and actionable remediation guidance.

Alert Integrations

Route alerts to your team's preferred channels: Discord, Slack, Microsoft Teams, or email. Configure routing per monitor—send security alerts to your security channel, uptime alerts to on-call, and dependency updates to a weekly digest.

Activity Logging

Every monitoring event is logged with full audit trails: scans started, completed, and failed; findings detected; URL status changes. The activity log provides visibility into your monitoring pipeline and helps with incident post-mortems.

The Complete Picture

With today's release, Paragon covers the full development lifecycle:

Code Review: Catch bugs at commit time with AI-powered analysis.

Testing: Validate functionality with E2E, integration, unit, and performance tests.

Monitoring: Ensure production health with uptime tracking, dependency scanning, and infrastructure checks.

Each capability integrates with the others. Failed tests can trigger monitoring alerts. Dependency vulnerabilities found in production can inform code review rules. The platform learns from your codebase and adapts to your team's patterns.

Getting Started

Both features are available now on home.polarity.cc. Existing Paragon users can access monitoring and testing from the dashboard. New users can sign up and connect their first repository in minutes.

The testing suite and monitoring features are included in Startup and Enterprise plans, with usage-based pricing for compute resources. See our pricing page for details on PCU rates for each operation.

What's Next

This release represents our vision for Paragon: a unified platform for software quality. We're continuing to invest in each pillar—deeper code review analysis, more testing capabilities, and expanded monitoring coverage.

Coming soon: API testing with contract validation, chaos testing for resilience verification, and mobile app testing support. We're also working on tighter CI/CD integrations and expanded language support for code review.
