SynapseKit spotlights fake async costs

The critique is useful, but the benchmarks read more like a framework founder’s field notes than an independently validated shootout.

• –Async correctness matters for FastAPI, serverless RAG, streaming agents, and local-model workloads where blocking calls quietly cap concurrency
• –The “two dependencies” positioning is sharp because cold starts are a real deployment tax, especially at edge and scale-to-zero boundaries
• –SynapseKit’s pitch lands hardest against LangChain-style abstraction stacks, where composability can come with harder tracebacks and more runtime indirection
• –The missing piece is reproducibility: developers will need public benchmark scripts, workload details, and apples-to-apples configs before treating the numbers as settled
