## Context

**Bitwarden** — Open-source password manager with hosted and self-hosted options. It currently costs $1.65/mo.

If your goal is to stop paying hosted Bitwarden Premium, the core vault can be self-hosted or replaced with KeePass-style local storage; the caveat is security responsibility.

This brief describes a focused, single-operator replacement for the part of Bitwarden that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

## What you are building

Use KeePassXC locally or self-host a Bitwarden-compatible server, keep encrypted backups, and use browser/mobile clients.

- Prototype the workflow, but rely on audited libraries and established security tools.
- A responsive interface with real empty, loading, success, and error states.

## Requirements

### Functional

- Server or local vault.
- Domain/HTTPS if self-hosting.
- Secure backup.
- Browser/mobile clients.

### Non-functional

- Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
- Security: server-side secrets, validated input, and no credentials in the client bundle.
- Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
- Portability: the operator can export their data and leave without losing it.

## Implementation brief

Build me a self-hosted password vault to replace hosted Bitwarden Premium.
Requirements:

- Do not write a password manager. Deploy vaultwarden (the Bitwarden-compatible
  server) on my VPS: a docker-compose.yml with the vaultwarden/server image
  and a data volume at ./vw-data.
- Front it with Caddy for automatic HTTPS on a subdomain I give you; the
  browser and mobile clients require HTTPS to work at all.
- Lock it down after I register my one account: SIGNUPS_ALLOWED=false, admin
  token in .env, nothing else exposed.
- Clients are the official Bitwarden apps and extensions pointed at my server
  URL. That is the point: autofill, mobile, and passkeys keep working.
- Nightly backup cron job: tar vw-data, encrypt it with age, copy it off the
  box. Write restore.sh and make me run one restore drill before trusting it.
- Import my existing vault with the standard Bitwarden export/import flow.
- Out of scope: emergency access, org and family sharing, and pretending I
  have a security team. Note in the README: clients cache the vault, so a
  dead server locks me out of nothing, but I now own updates and patching
  forever.
- README: compose up, first-account creation, update procedure, and the
  restore drill.

## Delivery standard

- Inspect the repository first, then write a short implementation plan before writing code.
- Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
- Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
- Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
- Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
- Add structured logs around every external call and return actionable errors without leaking sensitive details.
- Write unit tests for the core logic and one automated test of the main user journey.
- Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

## Acceptance criteria

- [ ] A clean install starts the app using only the README and .env.example.
- [ ] The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
- [ ] Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
- [ ] The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
- [ ] Tests, type checking, linting, and a production build all pass with no ignored failures.
- [ ] No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

## Non-goals

Do not build these, and do not claim to have replaced them:

- Managed hosting.
- Premium support.
- Emergency access.
- Polished admin.
- Trust, audits, and counterparties matter more than feature parity.
- Reliability at the vendor's scale is an operations problem, not a prompt.

## What you still own after launch

- Run migrations, backups, restores, and dependency updates.
- Test the critical journey after every model, API, or hosting change.
- Monitor failures and fix the edge cases a first prompt will miss.

## Risk

**High consequence.** Use this as a prototype or personal aid. Keep a qualified human and an established provider in the loop for consequential decisions.

Editorial confidence in this assessment: medium. No independent one-shot implementation is linked yet.

## Prior art

Working open-source software you can read, fork, or borrow from before starting:
