APIAssert vs Assertible

APIAssert vs Assertible

Assertible focuses on API testing and monitoring with powerful assertion capabilities. Here's how it compares to APIAssert.

Overview

Feature APIAssert Assertible
Focus Production API monitoring API testing + monitoring
Assertions Point-and-click builder Visual + code-based
CI/CD Webhook triggers Deep CI/CD integration
GraphQL First-class support Via HTTP
Pricing Starts at $9/mo Starts at $25/mo

When to Choose APIAssert

Choose APIAssert if you need:

  • Simple setup — monitors in minutes, not hours
  • Production monitoring focus — continuous health checks
  • GraphQL support — native query and mutation monitoring
  • Lower cost — more monitors for less money
  • Multi-region — 6 regions included on all plans

APIAssert is optimized for ongoing production monitoring. If you want to set up monitors quickly and have them run continuously, APIAssert makes it easy.

When to Choose Assertible

Choose Assertible if you need:

  • CI/CD integration — trigger tests on every deploy
  • Test suites — organize tests into logical groups
  • Data capture — extract values for use in other tests
  • Post-deploy testing — verify deployments immediately
  • GitHub integration — test status in pull requests

Assertible excels at post-deployment testing and CI/CD workflows. It's designed to verify your API after every code change.

Use Case Comparison

Continuous Production Monitoring

Goal: Know immediately when production APIs fail

APIAssert: ✅ Built for this

  • Set up monitors in minutes
  • Checks every 30 seconds if needed
  • Instant Slack/PagerDuty alerts

Assertible: ⚠️ Can do this

  • Minimum 15-minute intervals
  • More focused on post-deploy
  • Works but not optimized for continuous monitoring

Post-Deploy Verification

Goal: Verify APIs work after every deployment

Assertible: ✅ Built for this

  • Trigger tests from CI/CD pipeline
  • Update GitHub commit status
  • Block deploy if tests fail

APIAssert: ⚠️ Can do this

  • Webhook trigger available
  • But no native CI/CD integration
  • Won't block deployments

API Contract Testing

Goal: Ensure API responses match expected schema

APIAssert:

  • JSONPath assertions
  • Type checking
  • Value matching

Assertible:

  • Full JSON Schema validation
  • More comprehensive schema support
  • Regex pattern matching

Real-World Scenarios

Scenario: E-commerce Platform

Using APIAssert:

  • Monitor product API every minute
  • Alert if $.in_stock changes unexpectedly
  • Check from 3 regions simultaneously
  • Get Slack alert within seconds of failure

Using Assertible:

  • Test product API after each deploy
  • Validate full response schema
  • Run test suite from CI/CD
  • Block release if validation fails

Scenario: SaaS API

Using APIAssert:

  • Monitor all public endpoints continuously
  • Track response times over time
  • Multi-region latency awareness
  • Immediate PagerDuty escalation

Using Assertible:

  • Comprehensive test suite per endpoint
  • Post-deploy smoke testing
  • Capture auth tokens for chained tests
  • GitHub status integration

When to Use Both

Many teams use both tools:

  1. Assertible in CI/CD pipeline

    • Run comprehensive tests after each deploy
    • Validate API contracts
    • Block bad releases
  2. APIAssert for production

    • Continuous monitoring between deploys
    • Fast detection of runtime issues
    • Multi-region health checks

This gives you:

  • Deploy-time verification (Assertible)
  • Runtime monitoring (APIAssert)

The Bottom Line

Assertible is excellent for teams with mature CI/CD pipelines who want to validate API contracts on every deployment. Its deep integration with GitHub and CI tools makes it powerful for development workflows.

APIAssert is purpose-built for continuous production monitoring. If you need fast check intervals, multi-region monitoring, and instant alerts when things break in production, APIAssert is the simpler, more cost-effective choice.

Consider your primary need:

  • Post-deploy testing → Assertible
  • Continuous monitoring → APIAssert
  • Both workflows → Use both
