FlareMail vs Email Explorer is hosted versus a Workers project you run. Email Explorer is self-hosted, MIT, with 164 GitHub stars. It uses Workers, Durable Objects, R2, Email Routing, and Email Sending. The first registered user becomes admin, with roles Owner, Admin, Write, and Read. FlareMail is not that deploy. The codebase is not public.
Short answer: FlareMail is a web inbox for Cloudflare-powered email — a hosted inbox, while Email Explorer is a self-hosted Workers mail client that claims the free tier is enough for personal use.
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.
Email Explorer 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 | Email Explorer | |
|---|---|---|
| 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 on Workers, Durable Objects, and R2. The first registered user becomes admin. |
| Inbox | Browser inbox: read, folders, search, compose, attachments, labels, and privacy controls. | Rich text compose, reply and forward, custom folders, attachments, full-text search, and contacts. Roles are Owner, Admin, Write, and Read. |
| Send | Send from your domain in the same app. | Email Sending is part of the stack. Known limits: no draft auto-save, and image uploads are not supported. |
| Price | First 3 domains free. Pro is $10/month for 12 domains, then $1 per extra domain. Agency is $60/month unlimited. | The project claims the Cloudflare free tier is enough for personal use, with no subscription. You still operate the account. |
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 Email Explorer is actually good at
Email Explorer’s mail features are real: rich text compose, reply and forward, custom folders, attachments, full-text search, and contacts. It claims the Cloudflare free tier is enough for personal use, with no subscription. That claim is the project’s, and it is a genuine reason to look at self-hosting if your volume stays small.
The README also lists limits: no draft auto-save, and image uploads are not supported. Arbitrary scale and team process still sit on you, because you operate the Worker, Durable Objects, and R2.
Which one to pick
Pick Email Explorer when you want the bits in your account and you will operate them. Pick FlareMail when you want the inbox without becoming the person who provisions Worker, D1, and R2.
Start on onboarding and use the setup guide. First three domains are free. Pro is $10/month for 12 domains, then $1 per extra domain. Agency is $60/month unlimited.
