Spurt is a powerful stress testing tool designed to simulate high volumes of traffic and evaluate the performance and resilience of web servers. It has been tested on Linux.

Spurt first checks if the target URL is valid. A custom module is used to generate common "User-Agent" and "Referer" headers quickly, allowing it to make thousands of requests per second. Another module is used for multi-threading to send requests in parallel.

Make sure you have the following installed:

• Go
• Make
• Git

git clone https://github.com/zer-far/spurtcd spurtmake

./spurt --url https://example.com

Press Ctrl+C to stop Spurt.

• Option: --url string

• Description: Sets the target URL for requests.

• Option: --check

• Description: Checks your public IP address before using it for testing.

• Option: --cookie string

• Description: Uses a custom cookie.

• Option: --sleep int

• Description: Sets a delay (in ms) between requests to avoid rate limits.

• Default: 1 ms

• Option: --threads int
• Description: Specifies the number of threads for sending requests.
• Default: 1 thread

• Option: --timeout int
• Description: Sets a timeout (in ms) for each request to handle slow responses.
• Default: 3000 ms

./spurt --check --cookie"sessionid=123456" --sleep 10 --threads 2 --timeout 4000 --url https://example.com

This command uses the IP check, a custom cookie, a sleep time of 10 ms, 2 threads and a timeout ot 4000 ms.

• Spurt is intended for testing server performance under controlled conditions. It should not be used maliciously or for Denial of Service (DoS) attacks. Unauthorised use may lead to legal consequences.
• Your internet connection may slow down during use.
• Excessive requests may result in rate limiting or blocking.
• Avoid using on connections with limited bandwidth.
