Today I found web-framework written in ANSI C - G-WAN.
I like it, but it is not open source and maintained only by one developer. I am afraid of using it in production.
Do you know any more serious frameworks, that allow to write web services in ANSI C?
I am interested only in ANSI C, not C++.
UPD: I googled Raphters framework. Now I am cheking it out.
Working on G-WAN, I also value the ability to use C for a server.
Your pick, Raphters (like Nginx by the way), was also started "by one developer only".
But Raphters started in 2011 (is it more mature than G-WAN starting in 2009?) and the last update is almost one year old (is it better maintained than G-WAN?).
The author of Raphters says "G-WAN comes with more though". He might know better than us.
If you are looking for "any more serious frameworks, that allow to write web services in ANSI C" then look at Tuxedo, developed by AT&T in the 1980s.
After 30 years, Tuxedo is 'mature', 'well-maintained', and ORACLE (the new owner) is most probably here to stay.
But Tuxedo does not provide the performance of G-WAN (850,000 TPS). Below is the same weightp test on the same machine for Tuxedo (15,000 TPS and quickly dying despite the powerful hardware):
Concurrency / min / average / max
---------------------------------
1, 5477, 6151, 8161
10, 7894, 11416, 15451
20, 8177, 11894, 15578
30, 10064, 13246, 15499
40, 1, 909, 8885
50, 1, 18, 130

70, 1, 1, 1
80, 1, 1, 1
90, 1, 1, 1
100, 1, 1, 1
An ApacheBench (AB) test of Tuxedo confirms the test above (AB is slower than weighttp used above):

Looking at this, maybe you understand why G-WAN was created by its author: he could not find any Web framework able to port the Windows Desktop applications of his company to Web applications marketed as SaaS.
