Why people look for alternatives to sunpeak

The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.

OAuth support is incomplete; no standard way to pass Authorization headers.
Lack of Grok emulator, despite demand for it.
URL-backed state in the inspector is missing, hurting usability.
Learning curve for MCP newcomers; docs assume some familiarity.

In fairness: users also consistently praise convention-over-configuration auto-discovery cuts boilerplate significantly, and local inspector replicates chatgpt and claude runtimes for testing. A complaint list is not a verdict — see the full picture on the sunpeak page.
