Frequently asked questions

Load Curl is an API load testing platform that lets you simulate thousands of concurrent users against client URLs and API endpoints. Distributed workers generate realistic traffic while you watch live metrics and receive a graded performance report.

Load Curl is built for backend engineers, platform teams, and QA engineers who need fast, repeatable load tests without managing their own infrastructure. It works well for startups validating new endpoints and larger teams running regression tests before deploys.

Sign up for a free account, paste your API endpoint URL, configure auth headers and request body if needed, set your concurrent users and duration, then launch the test. Workers spin up across our network and results stream in real time.

No infrastructure setup is required for the dashboard workflow. You can configure and run tests entirely from the web UI. CLI and CI/CD integrations are available on paid plans for teams that want tests in their pipelines.

Today Load Curl supports REST and GraphQL endpoints with common authentication patterns. gRPC and WebSocket support are on the roadmap for future releases.

Yes. You can configure bearer tokens, API keys, custom headers, and request bodies when setting up a test. For multi-step flows, the scenario builder lets you chain endpoints with dependencies between calls.

Every test produces a letter grade (A through F) based on weighted metrics including latency percentiles, error rate, throughput, and stability. The report includes a detailed breakdown and recommendations for each failing dimension.

Yes. Load Curl uses a distributed worker swarm model. You can select target regions when configuring a load profile to simulate realistic geographic traffic patterns.

Pro and Enterprise plans include CI/CD integration with GitHub Actions, GitLab CI, and Jenkins. You can block deploys automatically when a load test fails your grade threshold.

Yes. The Starter plan is free and includes up to 50 concurrent workers, 5 test runs per month, 30-day result history, and report card grading. It is a good way to evaluate Load Curl before upgrading.

Pro ($49/mo) includes up to 5,000 concurrent workers, unlimited test runs, 12-month result history, PDF export, organization management for up to 10 seats, CI/CD integration, threshold alerts, and priority email support.

Yes. Enterprise is for teams that need 100,000+ concurrent users, dedicated worker clusters, SSO/SAML, custom data retention, audit log export, and a 99.99% SLA. Contact sales for custom pricing.

You can upgrade, downgrade, or cancel from your organization billing settings at any time. Plan changes take effect according to your billing cycle. See our Terms & Conditions for refund details.

Load testing production requires careful planning. We recommend starting with staging environments, using ramp-up periods, and setting conservative concurrency limits. Load Curl provides controls to avoid accidental overload, but you are responsible for testing systems you own or have permission to test.

Test configurations, results, and logs are stored securely on Load Curl infrastructure. Retention periods depend on your plan — 30 days on Starter, 12 months on Pro, and custom retention on Enterprise.

Auth tokens and API keys used in test configurations are encrypted in transit and at rest. We follow least-privilege access practices and never share your credentials with third parties except as required to operate the service.
