1. Move fast without breaking things
2. What is Gor? Open-source tool allowing you to re-use your existing users activity to test your apps http://gortool.com • In active development for 3+ years • 5500+ stars on Github • Trusted by hundreds of companies
 including large ones like: TomTom, theguardian or gov.uk • Commercially supported
3. How it works Gor able to capture application network traffic, and able replicate it to another endpoint, in real-time or on demand. Not a proxy: state of the art technology to silently capture traffic without affecting your application, e.g. no risk of placing 3-rd party component in the critical path
4. Capabilities • Perfect production emulation: content, calls flows, scenarios, volumes, same timing and order between the requests.
 • Modify the request content on the fly using built-in tools, to match your test environment requirements
 • Configurable request emission rate, to replicate not only actual load but simulate stress tests.
 • Implementing complex workflows using robust middleware support
5. Benefits • Test early, on production data, even without involving QA team • Repeatable test cases by reusing snapshots of your production traffic • Find edge-case issues before they are gone live: concurrency issues, requests called in a particular order, malformed user input etc. • The most accurate load testing, and does not require programming
6. Things to know • Implementing complex auth workflows can be challenging (if involves random token generation, which is hard to sync with your test environment) • If you have sensitive data you need to obfuscate it manually, using middleware or built-in tools • Adds additional CPU load to your server (depends on app, but usually few percents), and increased outbound network traffic
7. Community version • Support for HTTP traffic • Rate limiting and stress testing • Filtering and rewriting requests • Replaying from file • Middleware • License: LGPL
8. Pro version • Support for binary protocols like protocol buffers or Thrift • Saving and replaying directly from AWS S3 • Priority bug fixes • Dedicated email support • Commercial license (no custom terms) • Unlimited usage - $950 / year
9. Enterprise version • Distributed replaying and load testing • Increased security (TLS communication between Gor instances) • Feature requests • Phone / Skype support • Commercial license (with custom terms) • SLA • $1950 / year per 20 servers
