Show HN: Trayce - Burp Suite for developers
About a year ago I introduced Trayce to HN as the "network tab for
docker containers". Now I have released a new version which adds an
HTTP client. The idea is to combine network monitoring with an HTTP
client to help developers interact with and debug web application
servers. Think "Burp Suite for developers". Trayce stores
requests as local files using the .bru file format. The UI is based
on Flutter which means it offers a super-fast and modern desktop
GUI with a total download size of 13MB (on Linux). I am still
adding features to it so would love feedback. Currently the new
features in the pipeline are: OAuth2, GRPC, and scripting. It is
open source and free to use but a perpetual license must be
purchased for continued use. The license model is similar to that
of Sublime Text. Thank you!

| Great question! What differentiates Trayce from other HTTP
| clients are:
|
| - An ebpf-based network monitor which allows instant monitoring
| of HTTP(S), GRPC, MySQL, PostgreSQL. Most of those apps can
| only monitor HTTP using a proxy. Trayce does not use a proxy,
| it reads the traffic from the kernel layer.
|
| - UI is based on Flutter, not Electron or any other browser-
| based framework.
|
| - Local git-friendly HTTP request storage

| Trayce lets you import your .proto file to properly parse
