Is every Nitro app under 1MB?

The docs describe output under 1MB as a trait of the framework, not a promise for your app. Its size depends on what it includes, so we measure it.

How does a cached page refresh when Salesforce changes?

Nitro’s ISR supports on-demand refresh: a request with your bypass token in the x-prerender-revalidate header rebuilds that page. We call it from Salesforce when the record changes.

Can we see errors per route?

Yes, with Nitro 2.12 or later and compatibilityDate set to 2025-07-15 or later. Older apps get upgraded first.

Do we need Nuxt to use Nitro?

No. Nitro runs on its own as an API server. It is also what runs Nuxt’s server, and Vercel recommends it for running TanStack Start.

There is no Nitro price on Vercel. Its routes run as Vercel Functions on your plan. Hobby is for non-commercial, personal use only, so business webhooks need Pro or Enterprise.

A service desk team reads a chat message and opens a ticket while an old server rack is boxed up in the corner.

Vercel · Frameworks

Your WhatsApp and Salesforce webhooks live on a server nobody watches. Move them to Nitro, with no box to run.

There is usually a small API in the middle: it takes a WhatsApp message, a payment or a form and writes it to Salesforce. Nitro is a TypeScript server framework for that job, and it deploys to Vercel with zero configuration. Each route becomes a Vercel Function on Fluid compute, and pages that rarely change can be cached and refreshed on demand.

The problem

What the little API in the middle costs you today.

What Nitro is

Nitro, in plain words.

Facts from Vercel’s own pages, checked on 16 October 2026. The sources are at the end of this page.

What it is: A TypeScript-first full-stack framework with filesystem routing, code splitting for fast startup, built-in caching and multi-driver storage.
Setup: Nitro apps deploy to Vercel with zero configuration. vc init nitro starts one.
Where it runs: Server routes become Vercel Functions on Fluid compute by default.
Cache and refresh: ISR with on-demand refresh through a bypass token and the x-prerender-revalidate header, plus per-route ISR rules.
Errors per route: Per-route Observability needs Nitro 2.12 or later and a compatibilityDate of 2025-07-15 or later.
Under other frameworks: Nitro runs Nuxt’s server and is the recommended way to run TanStack Start on Vercel.

How it works

From a webhook on a VPS to routes you can watch.

Five steps. Each endpoint is a file, each file becomes a Function, and each change gets a preview before it touches live data.

Five steps: start the app, write one route per endpoint, set cache rules, deploy with previews, watch each route. — The same steps are written out below.

Step by step

What happens at each step.

Start
Start the app
Run vc init nitro, or import the repository.
Routes
Write the routes
One file per endpoint: a webhook, a status page, a form handler.
Rules
Set cache rules
ISR for pages that change rarely, refreshed on demand.
Deploy
Deploy with previews
Each route becomes a Function, and each change gets a preview.
Watch
Watch each route
Observability shows requests and errors route by route.

How it fits together

Where Nitro sits between WhatsApp, your forms and Salesforce.

Messages, payments and forms arrive at Nitro routes running as Vercel Functions. The routes write to Salesforce or your database. Vercel Firewall sits in front, and Observability shows each route’s errors.

WhatsApp, payments and forms reach Nitro routes on Vercel, which write to Salesforce and a database. — Where it sits next to the systems you run today.

How Nitro fits into the work of the industries we serve, one step at a time.

A WhatsApp message reaches a Nitro route, a Salesforce case opens and the client gets the case number. — Examples of the work, not client stories. Times in each example show the order of events, not a measured result.

A visa file moves in Salesforce, its cached status page refreshes on demand, and the client sees the new stage. — Examples of the work, not client stories. Times in each example show the order of events, not a measured result.

Is it for you

When Nitro fits, and when it doesn’t.

Good fit

Not for you yet

Webhooks or small APIs sit between WhatsApp, payments and Salesforce: Your API is written in Python: see FastAPI
Your team writes TypeScript: You need a full site with pages: Nuxt or TanStack Start sit on Nitro
Some pages change rarely but get many visits: A no-code tool already does the job and nobody needs to change it
You may change host later: Nitro deploys to many platforms: Your data must stay on servers in the UAE or Saudi Arabia

What Mindcat does

We build it, then we run it.

The assessment is free: a short read of the org and a written note. If you go ahead, the first build week is a fixed AED/SAR 14,900 (about USD 4,050), credited in full when you sign the build within 60 days. After go-live, we keep it patched, watched and changing every month.

01Move the webhooks off the old serverWe rewrite or port each endpoint as a Nitro route and switch the senders over.

02Connect WhatsApp and SalesforceSigned webhooks in, cases, leads or work orders out, with the keys kept in Vercel.

03Set cache and refresh rulesWhich pages are cached, and which Salesforce change refreshes them.

04Watch itErrors per route in Observability, and a named person who gets told when one fails.

05What it costsThe assessment is free. The first build week is a fixed AED/SAR 14,900. Monthly prices for looking after it are on one page.
