About HQBase

HQBase gives teams one place to work with shared mailboxes while keeping the application, mail, and Cloudflare credentials in customer infrastructure. It includes:

• Shared mailboxes and team access controls.

• Multi-domain setup, drafts, and audit history.

• Installation, update, backup, and recovery operations.

• An OAuth-protected remote MCP server.

See the product documentation for installation, daily use, architecture, and operations.

Made by the community

We love seeing people build around HQBase. Independent clients give you more ways to use your workspace:

• Herald — A native macOS email client for HQBase.

HQBase has tested Herald for compatibility. It is made and maintained by independent community developers, so its releases, support, and behavior remain in their care rather than HQBase's. Please review the project and decide whether it is right for your workspace.

Develop locally

Start the application

pnpm install
pnpm db:migrate:local
pnpm db:seed:local
pnpm dev

Before you run the optional seed command, add these values to .dev.vars:

• BETTER_AUTH_SECRET

• HQBASE_LOCAL_SEED_PASSWORD with 8 to 128 characters

The seed command writes only to local D1 and does not contact Cloudflare OAuth. Open http://127.0.0.1:5173/ and sign in as owner@hqbase.test with that password. Vite serves the frontend with live reload on port 5173 and proxies API requests to the Wrangler Worker on port 8787.

To use the first-run setup flow, omit the seed command and open http://localhost:5173/setup.

Reset local data

To discard all local D1 data, rebuild the schema, and recreate the demo workspace:

pnpm db:reset:local
pnpm db:seed:local

The reset command is destructive and local only. It does not change a deployed database.

Preview the setup interface

For presentation-only onboarding work:

pnpm dev:setup-ui

Open http://127.0.0.1:5173/__ui/setup.

Review the visual system

To inspect the shared components, interactive states, product patterns, and local screen routes:

pnpm dev:ui

Open http://127.0.0.1:5173/__ui/design. The gallery uses deterministic presentation fixtures and does not call product APIs.

Verify changes

Run the full local quality gate:

pnpm check
pnpm deploy:dry-run

Run pnpm cf:typegen after you change wrangler.jsonc.

Pushes to main run the same quality gate and deployment dry-run. Deployed staging is manual and also runs inside the signed release workflow. A release stays in draft until the previous stable version upgrades to the exact signed candidate and passes its checks. Customer installations and updates verify the signed manifest and artifact digest before deployment.
