# How to Vibe Code Your Own Backblaze (and Stop Paying for It)

> High-Performance Cloud Storage for AI Workloads and Computer Backup

- Site: https://backblaze.com
- Category: Cloud Storage & Backup
- Platforms: Web app, macOS app, Windows app
- Verdict: **Serious undertaking** (38/100 vibecodeable)
- Estimated effort: 6+ months of full-time work for a complete platform

## Verdict

Build a subset personal object storage dashboard and S3-compatible wrapper, but keep paying for production-scale backups and petabyte AI storage.

Replicating Backblaze's core value entails two entirely different engineering beasts: a distributed high-throughput S3-compatible storage backend and a bulletproof cross-platform native backup client. While you can easily spin up a Next.js web console fronting an open-source S3 gateway or local storage volume using AI tools, engineering high-density storage pods with hardware redundancy, erasure coding, and a low-level native background agent that reliably streams petabytes of endpoint files without crashing user machines requires massive systems-level engineering that far exceeds a typical vibecoded app.

### What you can't replicate

- Custom high-density hardware 'Storage Pods' and rack-level economics
- Exabyte-scale multi-datacenter infrastructure with 11 nines durability
- Enterprise compliance certifications (SOC 2 Type 2, HIPAA BAAs)

## What it does

Backblaze is an enterprise cloud storage and computer backup platform providing S3-compatible object storage and automated workstation backup.

### Core features

- S3-compatible object storage API endpoints
- Web console dashboard for bucket and file management
- Fine-grained API key and access control management
- Server-side encryption and client-side encryption keys
- Desktop background backup client for Windows and macOS
- Reed-Solomon erasure coding simulation for data durability

## The business

### Pricing

- B2 Cloud Storage: $6.95/TB/mo
- Computer Backup: Flat rate/mo

### Funding

$5.3M raised.
- Seed / Bootstrapped (2007-2012)
- Series A ($5M, 2012)
- Venture Debt / Convertible Rounds ($10M, 2020)
Investors: 2B Global

Founded 2007.
Team size: ~350.

## The hard parts

- Designing custom proprietary 'Storage Pod' high-density commodity server hardware
- Implementing low-level Reed-Solomon data striping and vault recovery mechanics
- Maintaining terabit-scale data pipeline throughput for massive AI/ML workloads
- Building a bulletproof, low-overhead native background desktop client that tracks file modifications without draining CPU or memory

## How to vibe code Backblaze

### Prerequisites

- Node.js (free): Runtime environment for building the web dashboard and API gateway.
- GitHub (free): Version control and deployment pipeline integration.
- Cloudflare Account (free): To host serverless functions and utilize R2 for S3-compatible object storage primitives.

### Recommended AI tools

- Claude Code: Unmatched capability for executing complex multi-file architectural scaffolding and debugging backend server code from the terminal.
- Cursor: Ideal for fine-tuning UI components, dashboard widgets, and reviewing code diffs visually.

### Stack

- Frontend: Next.js with Tailwind CSS
- Backend: Node.js / Express with MinIO or Cloudflare R2 bindings
- Database: Turso (SQLite at the edge)
- Auth: better-auth
- Payments: Stripe
- Other: Resend for email notifications

### Hosting

- Cloudflare (Hosting the Next.js web application frontend and leveraging Cloudflare R2 for S3 object storage compatibility.): $0-5/mo
- Fly.io (Running the custom backend storage gateway and API server daemon.): $5/mo

### Build guide

1. **Project Scaffolding & Authentication** — Initialize a Next.js project with Tailwind CSS, configure TypeScript, and set up better-auth for user account management and API token generation.

```
Scaffold a new Next.js 16 app with TypeScript and Tailwind CSS. Integrate better-auth with email/password credentials and SQLite (via Turso) for user persistence. Create a clean dashboard shell layout with sidebar navigation for Buckets, Account Settings, and API Keys.
```

2. **Database Schema & Key Management** — Design database tables for users, buckets, objects metadata, and fine-grained application keys with access permissions.

```
Using Drizzle ORM with Turso, define database schemas for users, storage buckets, stored object metadata (file name, size, content type, storage path, checksum), and API keys with permissions (read, write, delete). Build a settings page in the dashboard where users can generate and revoke S3-compatible Application Keys.
```

3. **S3-Compatible API Gateway** — Implement an Express backend service providing basic S3-compatible REST endpoints (PUT, GET, DELETE) authenticated via generated application keys.

```
Build an S3-compatible API gateway in Node.js/Express that supports authenticated PUT object, GET object, and DELETE object requests using AWS Signature V4 verification or custom application key headers. Store incoming binary streams directly to local disk volumes or Cloudflare R2 storage, and log transaction metadata into the database.
```

4. **Web Console File Browser** — Build the web user interface for browsing buckets, uploading files interactively, viewing storage usage metrics, and managing encryption settings.

```
Create a React-based file browser dashboard in Next.js that lists storage buckets, allows creating new buckets, supports drag-and-drop file uploads with progress indicators, and displays object metadata tables with deletion and download actions. Add a storage utilization analytics card summarizing total gigabytes stored.
```

5. **Security, Object Lock, & Encryption UI** — Add support for server-side encryption toggles and immutable object lock retention rules within bucket settings.

```
Extend the bucket settings UI and backend API to support Server-Side Encryption (SSE-B2 equivalent) and Object Lock (WORM retention rules). Ensure the database tracks retention timestamps and blocks file deletion requests when object lock is active.
```

6. **Background Backup Client Simulation** — Build a lightweight desktop utility script or daemon that monitors a local directory and periodically uploads modified files to your storage API clone.

```
Write a Node.js background watcher script using chokidar that monitors a local directory for file changes and automatically syncs newly created or modified files to your S3-compatible storage gateway API using chunked multipart uploads. Include retry logic and local state tracking to prevent duplicate uploads.
```

7. **Polish, Error Handling, & Deployment** — Conduct end-to-end integration testing, handle edge cases for large file streams, and deploy the stack to production hosting providers.

```
Implement robust error handling for network timeouts and large file uploads in both the frontend dashboard and API gateway. Add Sentry error monitoring, write comprehensive integration tests for bucket and object operations, and prepare deployment configurations for Fly.io and Vercel/Cloudflare.
```
