The visible email triage loop is buildable, but a credible replacement needs more than the first screen. SaneBox earns its keep through deliverability, security, integration, so expect a weekend or multi-day build and a narrower personal scope.

# SaneBox indie build

## Goal

Build the smallest trustworthy replacement for the core SaneBox workflow for one developer or a tiny team.

## Scope

Build a local email companion for email triage that works on exported mail or one user-authorized IMAP account.

## Quick start

1. Install the documented dependencies.
2. Copy `.env.example` to `.env`.
3. Run the development command chosen during implementation.
4. Complete the acceptance checks in `BUILD_PLAN.md`.

## Honest limits

This build deliberately does not replace:
- push reliability across devices
- team routing and shared inbox rules
- abuse response and security operations
- sender reputation, deliverability, and suppression handling
- provider-grade deliverability

If those capabilities are essential, use Mailspring instead of pretending the gap is solved.

why people still pay

SaneBox: Email is infrastructure. Customers pay to avoid lost messages, broken auth, spam problems, and the reputational cost of a flaky inbox.

questions
Vibecode SaneBox

Kinda. The core of SaneBox is buildable in a weekend with the prompt on this page, but there are real gaps: push reliability across devices, team routing and shared inbox rules. Read the honest list above before committing.

How much does SaneBox cost?

SaneBox's pricing is usage-based or varies by plan · The official pricing URL is recorded, but a stable current amount was not safely recoverable in this pass. Do not publish a number until rechecked..

What do I lose by replacing SaneBox?

Honestly: push reliability across devices; team routing and shared inbox rules; abuse response and security operations; sender reputation, deliverability, and suppression handling; provider-grade deliverability. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to SaneBox?

Yes: Inbox Zero (Server-side AI rules, follow-up tracking and bulk cleanup for Gmail or Outlook; self-hosting starts with OAuth, Docker and a model.) The prompt is for when you want it exactly your way.
