SelfHeal vs NeuralBridge: Two Philosophies of AI API Self-Healing

If your AI API fails at 3 AM, do you send the patient to a clinic — or does the immune system handle it in-place?

That's not a rhetorical question. It's the architectural decision at the heart of every AI self-healing tool today. Two projects answer it differently: SelfHeal routes your traffic through an external proxy. NeuralBridge embeds self-healing directly into your code. Same destination, fundamentally different journeys.

I've spent time with both. Here's what I found.

The Problem: Four Ways Your AI API Dies

Before comparing tools, let's name the failures. AI API errors fall into four buckets:

Rate limiting (429) — Your agent hammers an endpoint. The provider throttles. Your retry loop makes it worse.

Timeouts — One slow upstream in a chained pipeline poisons every downstream call. Your agent sits idle.

Model unavailability — The provider's model goes down.…
