Run API Backends as Tor Hidden Services
APIs are the backbone of modern applications, but exposing them on the clearnet reveals server locations and creates attack surfaces. Running your API backend as a Tor hidden service provides an extra layer of anonymity and security for both the API provider and consumers. AnubizHost offers Tor hosting optimized for API workloads on the .onion network.

Why Host APIs on Tor?
There are compelling reasons to operate API backends as Tor hidden services rather than on the clearnet:
- Server anonymity — The .onion address hides the API server's IP address and physical location, preventing targeted attacks
- DDoS resistance — Tor hidden services are harder to DDoS than clearnet servers because the real IP is never exposed
- Client anonymity — API consumers connect through Tor, hiding their identity from the API provider
- Access control — Limit API access to Tor users only, creating a natural barrier against automated scanners and bots
- Internal service mesh — Connect microservices to each other via .onion addresses for encrypted, authenticated internal communication
This architecture is particularly valuable for privacy-focused applications, cryptocurrency services, and sensitive data processing systems.
Supported API Frameworks and Languages
AnubizHost's Tor hosting supports any API framework and language. Common deployments include:
- Node.js — Express, Fastify, NestJS, or Koa APIs with WebSocket support for real-time features
- Python — Flask, FastAPI, or Django REST Framework for data-heavy API backends
- Go — Gin, Echo, or Fiber for high-performance APIs with minimal resource usage
- Rust — Actix-web, Rocket, or Axum for maximum performance and memory safety
- PHP — Laravel, Symfony, or Slim for rapid API development
Each deployment is configured with nginx as a reverse proxy, handling TLS termination (HTTPS over Tor), request buffering, and connection management optimized for Tor's latency characteristics.
API Security on Tor
Running APIs on Tor adds a layer of obscurity, but defense-in-depth security remains essential:
- Authentication — JWT tokens, API keys, or .onion client authentication to verify authorized consumers
- Rate limiting — Prevent abuse with per-client rate limits enforced at
nginxand application levels - Input validation — Strict input validation to prevent injection attacks (SQL, NoSQL, command injection)
- CORS configuration — Properly configure Cross-Origin Resource Sharing for .onion domains
- Logging without PII — Log API requests for debugging without recording client IP addresses or personally identifiable information
- Encrypted database connections — TLS-encrypted connections between API and database, even on the same server
