FlareMail vs Quickinbox is hosted versus a Workers app you run. Quickinbox is self-hosted, MIT, with 407 GitHub stars. It is a full web client on Workers with D1 and R2. FlareMail does not ask you to create those resources. You open the app and connect a domain. One step sits outside the app: an Email Routing rule to the flaremail-api Worker.
Short answer: FlareMail is a web inbox for Cloudflare-powered email — a hosted inbox, while Quickinbox is a self-hosted Workers client you deploy and wire to DNS.
Cloudflare email inbox in your browser. First three domains free. Pro is $10/month for 12 domains, then $1 per extra domain. Agency is $60/month unlimited.

Hosted inbox or a stack you operate
FlareMail is for people who already run on Cloudflare and do not want to provision the mail stack. You create an account, open the app, and connect a domain. The setup guide says about five minutes. One step sits outside the app: an Email Routing rule to the flaremail-api Worker. FlareMail operates the Worker, D1, and R2.
Quickinbox is the self-hosted path in this comparison. You clone it and you keep it running. That can be the right trade when the mail must live in your Cloudflare account, or when a feature below is the reason you are here.
Side by side
Same job, different operator. Price on the FlareMail side is the domain plan, not a claim that self-hosting is free.
| FlareMail | Quickinbox | |
|---|---|---|
| Where it runs | Hosted. Create an account and open the app. | Self-hosted. You deploy and operate it. |
| Who operates Worker, D1, and R2 | FlareMail operates the Worker, D1, and R2. | You do. |
| Setup | Connect a domain in the app. The setup guide says about five minutes, with one step outside the app: an Email Routing rule to the flaremail-api Worker. | Self-hosted. The setup wizard budgets about 30 minutes, mostly DNS. |
| Inbox | Browser inbox: read, folders, search, compose, attachments, labels, and privacy controls. | Full web client: threads, attachments, multi-domain, and multi-user, plus REST, CLI, and hosted MCP with OAuth. |
| Send | Send from your domain in the same app. | Resend by default, or Cloudflare Email Service. Cloudflare sending requires a Workers paid plan. Optional web push and Telegram. |
| Price | First 3 domains free. Pro is $10/month for 12 domains, then $1 per extra domain. Agency is $60/month unlimited. | No FlareMail fee. You pay Cloudflare and the sending provider you configure. |
What the FlareMail screen actually is
The inbox list above is the web app from this product, with obviously fake mail so the screenshot does not use a customer account. The sign-in form at app.sendwithflare.com is only the account door. It is not the inbox.
What Quickinbox is actually good at
Quickinbox’s strengths are the product surface and the interfaces around it. Threads, attachments, multi-domain, and multi-user are in the client. It also exposes REST, a CLI, and a hosted MCP with OAuth. Optional web push and Telegram are documented. The provider is Resend by default, or Cloudflare Email Service. The Cloudflare sending path requires a Workers paid plan.
The setup wizard budgets about 30 minutes, mostly DNS. That is a fair budget for a self-hosted mail stack. FlareMail’s setup guide says about five minutes, because the Worker, D1, and R2 are already running.
