Relia: tracing + plain-English incident reports for Hono (Node, Workers, Deno)

[virajrakholiya]

Hi all. I'm building Relia, a monitoring tool for small teams that don't have an SRE. Hono was one of the frameworks I most wanted to get right, so I'm sharing it here and asking for feedback.

Setup

On Node, npx relia-sdk@latest init detects a Hono API and adds tracing for you.

On Workers or Deno, you wrap the fetch handler:

import { Hono } from "hono"
import { withRelia } from "relia-sdk/edge"

const app = new Hono()
app.get("/users/:id", (c) => c.json({ ok: true }))

export default { fetch: withRelia(app.fetch) }

What gets recorded

• Each request becomes one span with the route template, status, duration and the error behind any failure.
• fetch calls made inside a request become child spans.
• Model calls made with fetch (OpenAI, Anthropic, Gemini, OpenRouter) are grouped into one AI run per request, with token counts and cost.
• It has no dependencies and uses only web APIs.

Relia learns what normal looks like for each route. When something drifts, it tells you in plain words what broke, who it affected and where to look. It explains and suggests fixes. It never changes your code.

There's a demo you can try without signing up: https://app.tryrelia.com/demo?utm_source=github&utm_campaign=lead-agent

My question: if you run Hono in production, what's the first thing you check when a route starts failing? I'd like Relia's alerts to start from that.
