sish VS BitDive

• Open Source
  sish is open-source, allowing users to inspect, modify, and contribute to the project's codebase.
• Self-Hosted
  Users can host their own instance of sish, giving them complete control over their tunneling service and associated data.
• Simple Setup
  The installation and setup process for sish is straightforward, requiring minimal configuration to get started.
• Custom Subdomains
  sish allows users to utilize custom subdomains for their tunnels, enhancing branding and easier access.
• Security Features
  Built-in support for TLS and authentication options, ensuring that tunnels are secure and accessible only to authorized users.
• Portability
  sish supports multiple platforms, allowing it to be used in various environments such as local development, testing, or cloud deployment.

Possible disadvantages

• Self-Management
  Users need to manage their own server and configurations, which can require additional maintenance and oversight compared to managed services.
• Resource Consumption
  Hosting your own instance of sish requires computational resources, which could be a con if the service is heavily used.
• Complexity for Non-Developers
  Non-developers might find the setup and maintenance process challenging without prior experience in server management and configuration.
• Limited Community Support
  As a niche project, sish may not have as large of a community or as many resources available for troubleshooting as more popular alternatives.
• No Built-In Analytics
  Unlike some other tunneling services, sish does not provide built-in analytics or monitoring tools, requiring users to implement their own solutions.

• Heatmap
  Performance heatmap highlighting slow endpoints and hotspots across services.
• Service Map
  Service map showing microservice dependencies and request paths across the system.
• Error Debugging (method-level)
  Error Debugging (method-level): Method-level call tree with parameters, exceptions, and SQL for log-less root cause analysis.
• Create Tests
  Create replay tests in a few clicks from captured executions, no test code or mock maintenance.

Create unit tests automatically from real microservice traces with BitDive Replay. In this demo, I generate JUnit tests (run via Maven) from recorded calls, complete with mocks and inputs, then run them locally and in CI/CD using mvn test.

• Self-hosted HTTP tunnels with SSH and Nginx

  A number of years ago, I created a fully open source (MIT) project called sish [0] that does just this. Sish is a SSH server written specifically for tunneling. You get all of the benefits of SSH, but also automatic TLS, a web console of... - Source: Hacker News / 15 days ago

• Pico.sh (The ultimate SSH powered services for developers)

  We’re actually using Unix sockets as the underlying transport layer for this. We’re also not using sshd, we custom wrote our own daemon that’s entire job is tunneling. If you’re curious about this, you can find the project here:... - Source: Hacker News / over 1 year ago
