## Pages

- [JWT Authorization](https://docs.speedscale.com/concepts/auth/index.md): Implement JWT Authorization with Speedscale to handle token expiration during traffic replay and customize your testing for various authorization patterns.
- [Capturing Traffic](https://docs.speedscale.com/concepts/capture/index.md): Capture application traffic with Speedscale to enhance API testing, load testing, and chaos testing using real data for accurate diagnostics and replays
- [Chaos Engineering (API)](https://docs.speedscale.com/concepts/chaos/index.md): Explore how to implement Chaos Engineering with Speedscale to test API resilience by simulating failures and manipulating request behaviors for robust applications
- [Database traffic](https://docs.speedscale.com/concepts/database-traffic/index.md): What Speedscale and proxymock record about each database call your services make: the statement and its bound values, who ran it on which connection, how it ended, and the request that ran it, with no access to the database.
- [Bubble Environments](https://docs.speedscale.com/concepts/ephemeral/index.md): Create and manage Bubble Environments with Speedscale to mimic production settings, reducing costs and enhancing testing efficiency for your development workflow
- [Filters and Subsets](https://docs.speedscale.com/concepts/filter/index.md): Explore how to use Filters and Subsets in Speedscale to manage recorded traffic, ensuring data privacy and enhancing analysis capabilities.
- [Inner vs Outer Loop](https://docs.speedscale.com/concepts/inner-outer/index.md): Understand the differences between inner and outer loops in software development and how Speedscale enhances productivity by simplifying environment replication tasks.
- [Replaying Traffic](https://docs.speedscale.com/concepts/replay/index.md): Replay real traffic with Speedscale by generating and responding to captured requests, enabling effective API testing and issue diagnosis in your applications.
- [Schedules](https://docs.speedscale.com/concepts/schedules/index.md): Create and manage schedules in Speedscale to automate actions like snapshots and replays, enhancing your API testing and traffic replay processes.
- [Service Mocking](https://docs.speedscale.com/concepts/service_mocking/index.md): Implement service mocking with Speedscale to simulate external APIs and databases, ensuring realistic responses for your microservices during testing.
- [Test Configs](https://docs.speedscale.com/concepts/test_config/index.md): Configure traffic replay settings with Test Configs in Speedscale, allowing you to customize templates for efficient API testing and integration.
- [Transforms](https://docs.speedscale.com/concepts/transforms/index.md): Modify captured requests and responses with shared transform chains in Speedscale Cloud templates and proxymock blueprints.
