What is the best way to fix broken tool calls in self-hosted coding agents?

The best way is usually to add a proxy layer between the client and the model runtime. That lets you normalize stream events, repair malformed tool-call output, and handle hangs without forcing every client or runtime to implement the same fixes.

Is an LLM tool-call reliability proxy worth building as a SaaS?

Yes, for a focused niche. The buyers are not all AI developers, but the subset using self-hosted coding models in real workflows feels this pain sharply enough to pay for stability and debugging visibility.

How do you make OpenAI-compatible local LLM servers work with coding assistants?

You make them work by smoothing over the differences that “compatible” often hides. In practice that means translating stream formats, handling reasoning-token quirks, repairing partial function calls, and exposing a predictable endpoint the coding assistant already understands.

Who would pay for a proxy that repairs malformed LLM function calls?

Power users, indie developers, consultants, and small engineering teams are the most likely buyers. They already spend time maintaining self-hosted setups, so paying to remove a recurring failure point is easier to justify than for casual users.

Can open-source tools solve LLM streaming and tool-call reliability on their own?

They can solve parts of it, but usually not the whole compatibility mess. The hard part is ongoing maintenance across many model, runtime, and client combinations, plus good diagnostics when something still breaks.

How much could you charge for a self-hosted LLM compatibility proxy?

A low monthly tier for solo developers and a higher team tier is the sensible starting point. The value comes from saved debugging time and fewer broken coding sessions, so pricing should stay comfortably below the cost of even a few hours of engineer frustration each month.
