Getting Started
Prerequisites
1. Install dependencies
2. Start PostgreSQL
3. Configure environment
The defaults work out of the box for local development. Edit .env to change the storage provider or add OAuth credentials.
4. Run database migrations
pnpm db:generate pnpm db:migrate
5. Start the dev server
Open http://localhost:3000, create an account, and start uploading files.
Self-Hosting Guide
Locker auto-detects which platform it's running on and adjusts its capabilities accordingly. Persistent runtimes (Docker, Fly.io, Railway) support all features. Serverless runtimes (Vercel) disable long-running operations like store sync and bulk KB ingestion.
Requirements
Every deployment needs:
- PostgreSQL 16+ — the primary database
BETTER_AUTH_SECRET— generate withopenssl rand -base64 32NEXT_PUBLIC_APP_URL— the public URL of your deployment- A storage provider — local filesystem (persistent runtimes only) or a cloud provider (S3, R2, Vercel Blob)
Docker Compose (recommended)
The included docker-compose.yml bundles PostgreSQL, migrations, and the web app. This is the fastest way to self-host.
# 1. Clone and configure git clone https://github.com/zmeyer44/Locker.git && cd Locker cp .env.example .env # 2. Set the required secret # Replace the placeholder in .env or export it: export BETTER_AUTH_SECRET=$(openssl rand -base64 32) # 3. Start everything docker compose up -d
Open http://localhost:3000. Files are stored on a Docker volume (blob_data) by default.
To use S3 or R2 instead of local storage, set BLOB_STORAGE_PROVIDER and the matching credentials in your .env before starting.
To enable optional search services:
docker compose --profile search up -d
Railway
Railway provides managed PostgreSQL and persistent disk, so all features work out of the box.
-
Create a new project and add a PostgreSQL service. Copy the
DATABASE_URL. -
Add a new service from the Locker repo. Railway will detect the
Dockerfileautomatically. -
Set these environment variables on the web service:
Variable Value DATABASE_URLThe PostgreSQL connection string from step 1 BETTER_AUTH_SECRETopenssl rand -base64 32BETTER_AUTH_URLYour Railway public URL (e.g. https://locker-production.up.railway.app)NEXT_PUBLIC_APP_URLSame as BETTER_AUTH_URLBLOB_STORAGE_PROVIDERlocal(default) ors3/r2with matching credentials -
If using local storage, attach a volume mounted at
/app/local-blobs. -
Deploy. Railway runs migrations automatically via the
migrateservice in Docker Compose, or you can add a deploy command:pnpm db:migrate && node apps/web/server.js.
Fly.io
Fly provides persistent VMs with attached volumes.
-
Create a PostgreSQL cluster:
fly postgres create --name locker-db
-
Launch the app from the repo root:
fly launch --dockerfile Dockerfile
-
Attach the database:
fly postgres attach locker-db
-
Create a volume for local storage:
fly volumes create blob_data --size 10 --region your-region
Add to
fly.toml:[mounts] source = "blob_data" destination = "/app/local-blobs"
-
Set secrets:
fly secrets set \ BETTER_AUTH_SECRET=$(openssl rand -base64 32) \ BETTER_AUTH_URL=https://your-app.fly.dev \ NEXT_PUBLIC_APP_URL=https://your-app.fly.dev
-
Run migrations and deploy:
Render
- Create a PostgreSQL database in Render. Copy the internal connection string.
- Create a new Web Service from the Locker repo. Set the Dockerfile path to
./Dockerfile. - Add a Disk mounted at
/app/local-blobsfor local file storage. - Set environment variables:
DATABASE_URL,BETTER_AUTH_SECRET,BETTER_AUTH_URL,NEXT_PUBLIC_APP_URL. - Deploy.
Vercel
Vercel runs Next.js on serverless functions. Locker auto-detects this and disables features that require a persistent runtime:
- Store sync and ingest are disabled
- Bulk KB ingestion is disabled
- Local filesystem storage is unavailable
You must use a cloud storage provider (Vercel Blob, S3, or R2).
-
Import the repo into Vercel.
-
Set the framework preset to Next.js and the root directory to
apps/web. -
Add a PostgreSQL database (Vercel Postgres, Neon, Supabase, etc.) and set
DATABASE_URL. -
Set environment variables:
Variable Value BETTER_AUTH_SECRETopenssl rand -base64 32BETTER_AUTH_URLYour Vercel deployment URL NEXT_PUBLIC_APP_URLSame as BETTER_AUTH_URLBLOB_STORAGE_PROVIDERvercel(recommended) ors3/r2BLOB_READ_WRITE_TOKENFrom Vercel Blob (if using vercelprovider) -
Deploy. Run migrations manually or via a build command:
pnpm db:migrate && pnpm build.
Runtime override
Locker detects the hosting platform automatically from environment variables (VERCEL, FLY_REGION, RAILWAY_ENVIRONMENT, etc.). If detection is wrong or you want to test serverless behavior locally, set:
LOCKER_RUNTIME_ENV=vercel # or: docker, fly, railway, render, developmentStorage
Platform default
Set BLOB_STORAGE_PROVIDER in .env to configure the default storage backend for new workspaces:
| Provider | Value | Required Env Vars |
|---|---|---|
| Local filesystem | local |
LOCAL_BLOB_DIR |
| AWS S3 | s3 |
AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, S3_BUCKET |
| Cloudflare R2 | r2 |
R2_ACCOUNT_ID, R2_ACCESS_KEY_ID, R2_SECRET_ACCESS_KEY, R2_BUCKET |
| Vercel Blob | vercel |
BLOB_READ_WRITE_TOKEN |
Multi-store
Workspace admins can attach additional stores from Settings > Stores. Each store can be configured as:
- Writable replica — files are automatically synced to this store for redundancy
- Read-only ingest — Locker scans the store for new files and imports them without moving the originals
Stores use their own credentials (BYOB), so different teams can bring different backends. A primary store is designated per workspace for new uploads; replicas receive copies automatically.
Plugins
Locker ships with a built-in plugin system. Plugins are installed per-workspace and can add search, transcription, file actions, and more.
| Plugin | Description |
|---|---|
| QMD Search | Semantic document search powered by QMD embeddings |
| Full-Text Search | Lightweight SQLite FTS5 search — no external service required |
| Document Transcription | AI-powered OCR for images and PDFs, making non-text files searchable |
| Google Drive Sync | Import files from and export files to Google Drive |
| Knowledge Base | Build an AI-powered wiki from tagged documents with chat and graph view |
Optional search services
QMD and FTS run as standalone microservices. Enable them with the search Docker Compose profile:
docker compose --profile search up -d
Scripts
| Command | Description |
|---|---|
pnpm dev |
Start all packages in dev mode |
pnpm build |

Virtual Filesystem Shell API
Locker includes a read-only virtual filesystem over workspace files/folders, powered by just-bash.
The shell API is available on tRPC router vfsShell:
vfsShell.createSession({ cwd? })→ create a workspace-scoped shell sessionvfsShell.exec({ sessionId, command, timeoutMs? })→ run a bash commandvfsShell.session({ sessionId })→ get sessioncwd+ expiryvfsShell.closeSession({ sessionId })→ close a session
Implementation details:
- Directory tree is bootstrapped from
folders+filesand cached in memory. - File contents are fetched lazily from the configured storage provider and cached.
- All write operations (
rm,mv, redirections, etc.) fail withEROFS(read-only filesystem). - Access is workspace-scoped and enforced by existing workspace membership checks.
