Compare included quotas, restrictions and official provider documentation.
3 collections with 100 records each; 1,000 GET requests/month; 50 POST inserts/day; 3 AI API Builder uses/month
Free is $0 forever without a card. Production base URLs and relationships require Starter; when a quota is exhausted, further mock requests can return HTTP 429 until upgrade or the billing cycle resets.
5,000 billed visual-test snapshots/month (equivalent to up to 25,000 TurboSnaps); Chrome browser; unlimited projects, users and collaborators
Visual review and testing pause at the monthly snapshot cap until reset or upgrade. Safari, Firefox and Edge testing require a paid plan; explicit commercial-use terms unconfirmed.
50 requests/day per public endpoint; 3 mock rules; 10 small CRUD objects; dynamic and conditional responses; ephemeral local tunnel
Free endpoints are public, with no SLA. Unclaimed endpoints are automatically deleted (official pages differ between 7 and 30 days); claimed endpoints expire 90 days after creation. Do not send sensitive payloads.
Unlimited local mock API servers, routes and requests using the free desktop app, CLI or Docker image; OpenAPI import/export and CI integration.
Local-first MIT-licensed edition; infrastructure for remote deployment is self-funded. Real-time team collaboration, centralized administration, managed deployments and browser workspace require paid Mockoon Pro; its 14-day trial is not the free edition.
Free Apache-2.0 command-line HTTP client and integration-test runner; unlimited locally executed HTTP requests and tests without a vendor account.
Requests consume your own network and target-service quotas; no hosted API or testing infrastructure is included. Runs locally or in user-provided CI.
Free Apache-2.0 open-source HTTP API mocking and stubbing server, available as standalone Java JAR, Docker container or library; no software request or project quotas.
Self-hosted software only: server compute, storage and networking may cost money. WireMock Cloud hosted mocking and enterprise features are separate offerings; no hosted cloud allowance is included.
AGPL-3.0 open-source CLI for JavaScript-based performance and load testing on your own machine or CI runner; no software test-run or virtual-user quota.
Generating load uses your own CPU, network and CI resources; target service usage and bandwidth may be billed. Grafana Cloud k6 hosted tests and enterprise features are separate paid offerings; AGPL-3.0 terms apply.
Free local CLI for natural-language web, Android and iOS testing, with persistent memory and self-improvement, for FSL-permitted use.
Requires Node.js 24+ and your own model inference and execution infrastructure; optional cloud-device services cost extra. FSL-1.1-ALv2 restricts competing commercial use. Provider billing/card requirements vary.
