AuroraX

A self-hosted gateway that puts one OpenAI- and Anthropic-compatible API in front of many LLM providers.

14 provider types • OpenAI & Anthropic compatible • Go • Apache 2.0

What it does

AuroraX sits between your app and LLM providers. Your app talks the standard OpenAI or Anthropic API — the gateway routes each request to whichever provider you've configured. One format handles everything.

# Before: hardcoded provider
client = OpenAI(base_url="https://api.openai.com/v1", api_key="sk-...")

# After: AuroraX
client = OpenAI(base_url="http://localhost:8080/v1", api_key="your-aurorax-key")

No SDK changes. No format changes. Just swap the base_url.

Features

Routing & providers

• 14 provider types — OpenAI, Anthropic, Gemini, Groq, DeepSeek, OpenRouter, xAI, Z.ai, MiniMax, Azure OpenAI, Oracle, Ollama, vLLM, Jina
• Auto-discovery — set a provider's _API_KEY, restart, provider and models appear
• Per-provider model auto-fetch toggle, filter (substring / regex / price), custom User-Agent and base URL
• Provider pools — round-robin or weighted distribution, health-aware failover
• Egress control — source IPs with a live per-IP inventory (state, traffic, pause/resume), extension endpoints joined to the pool's providers
• Fallback chains — automatic failover on 5xx/429 plus editable manual rules
• Model aliases & overrides, passthrough routes (/p/{provider}/*)
• Resilience — exponential backoff with jitter, per-provider circuit breaker

API surface

• OpenAI-compatible: /v1/chat/completions, /v1/embeddings, /v1/rerank, /v1/models, /v1/files, /v1/batches
• Responses API (/v1/responses) and Anthropic-compatible /v1/messages
• SSE streaming end-to-end, keep-only-aliases and allowlist model modes

Caching

• Exact cache (SHA-256, Redis), semantic cache (Qdrant / pgvector / Pinecone / Weaviate)
• Prompt cache — forwards native cache_control with modes and thresholds
• Model registry cache — local filesystem + Redis, offline-safe

Security & guardrails

• Master key, managed API keys with per-key rate limits and model authorization
• Provider-scoped API keys — pick a provider and the key covers every model it serves, including models discovered after the key was issued (groq/* in allowed_models, or just the provider switch in the dashboard)
• PII redaction, prompt-injection blocking, system prompt protection, regex blocking
• Length limits and LLM-based altering, with input/output direction and ordering

Observability

• Audit logging (configurable retention, live SSE stream), usage analytics with cost tracking
• Prometheus metrics, structured logging, pprof endpoints
• Admin dashboard built into the Go binary — full provider CRUD, pools, fallback, guardrails, cache, usage, audit, workflows, console, playground

Cost control

• Token saver — policy-driven output compression (concise, caveman, ultra, wenyan)
• Per-model pricing overrides, usage budgets per key

Performance

• Streaming-first Go request paths; session mapping resolves in well under a microsecond per request
• Benchmarked against a mock OpenAI-compatible upstream at 5,000 RPS (60 s runs, median of three, Intel i5-10300H): 4,986 req/s, 100% success rate, P50 17.7 ms, P99 47.2 ms

Session Hub — header transformation engine with per-provider/pool session mapping, 7 header modes (map, map_or_generate, generate, passthrough, static, random_from_list, remove), configurable charset, disk persistence and live editing. Full reference: documentation/SESSION_HUB.md.

Sidecar — bundled Bun proxy for extension-driven TLS fingerprinting with multi-IP egress (one CONNECT proxy per source address, rotated per request so rate limits spread across addresses) and extension-supplied headers, tools and retries. Full reference: documentation/SIDECAR.md.

Extensions & store — portable JSON bundles that configure the sidecar and Session Hub in one apply; ship tool schemas, identity headers, auth defaults and optional provider types. Install from a store or by URL (POST /sidecar/extensions/import), then apply from Settings → Sidecar. Review extensions before installing them.

Quick start

1. Run the gateway

docker run -d --name aurora -p 8080:8080 \
  -e AURORA_MASTER_KEY="your-secure-key" \
  -e OPENAI_API_KEY="sk-..." \
  -e ANTHROPIC_API_KEY="sk-ant-..." \
  entbtw/aurora:latest

Or from source: go build -o aurora ./apps/aurora && ./aurora (aurora init scaffolds config.yaml, .env and data/).

2. Verify

curl -s http://localhost:8080/health          # {"status":"ok"}
open http://localhost:8080/admin/dashboard    # add a provider

3. Test a model call

curl http://localhost:8080/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-master-key" \
  -d '{"model":"groq/llama-4-scout-17b-16e-instruct","messages":[{"role":"user","content":"Hello!"}]}'

Anthropic format with streaming:

curl http://localhost:8080/v1/messages \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your-master-key" \
  -H "anthropic-version: 2023-06-01" \
  -d '{"model":"anthropic/claude-sonnet-5-20260630","max_tokens":1024,"stream":true,"messages":[{"role":"user","content":"Hello!"}]}'

Providers

Providers are auto-discovered from environment variables. Set a _API_KEY and restart — the provider and its default models appear.

Provider	Env var	Default base URL	API key
OpenAI	OPENAI_API_KEY	https://api.openai.com/v1	required
Anthropic	ANTHROPIC_API_KEY	https://api.anthropic.com/v1	required
Google Gemini	GEMINI_API_KEY	https://generativelanguage.googleapis.com/v1beta/openai	required
Groq	GROQ_API_KEY	https://api.groq.com/openai/v1	required
DeepSeek	DEEPSEEK_API_KEY	https://api.deepseek.com	required
OpenRouter	OPENROUTER_API_KEY	https://openrouter.ai/api/v1	required
xAI (Grok)	XAI_API_KEY	https://api.x.ai/v1	required
Z.ai	ZAI_API_KEY	https://api.z.ai/api/paas/v4	required
MiniMax	MINIMAX_API_KEY	https://api.minimax.io/v1	required
Azure OpenAI	AZURE_API_KEY	— (requires base URL + AZURE_API_VERSION)	required
Oracle	ORACLE_API_KEY	— (requires base URL)	required
Ollama	OLLAMA_API_KEY	http://localhost:11434/v1	optional
vLLM	VLLM_API_KEY	http://localhost:8000/v1	optional
Jina (reranker)	JINA_API_KEY	— (requires base URL)	required

Handy knobs:

OPENAI_MODELS=gpt-5.6-sol,gpt-5.6-luna        # override auto-discovered models
OPENAI_BASE_URL=https://proxy.example.com/v1  # custom endpoint
OPENAI_EAST_API_KEY=sk-...                    # → provider openai-east

YAML providers add user_agent, auto_fetch_models, autofetch_filter (substring / regex / price conditions), bind_ip and pool_only — see Deployment and Multi-account pools.

Secrets go in your .env file (gitignored) or your secrets manager — never commit them.

Configuration

Priority (later wins):

code defaults → config.yaml → .env / environment variables

aurora init generates config.yaml with every section documented inline:

Section	What it controls
server	Port, base path, master key, passthrough, Anthropic ingress
admin	Dashboard API and UI
models	Discovery, overrides, allowlisting
storage	SQLite (default), PostgreSQL, or MongoDB
logging	Audit logging of requests/responses
usage	Token tracking, pricing, retention
metrics	Prometheus endpoint
guardrails	Content safety filters
cache	Model cache, response cache (exact + semantic)
combos	Multi-model combo definitions
token_saver	Output compression
fallback	Provider failover rules
resilience	Retry + circuit breaker
workflows	Policy-based request routing

Pre-built profiles in configs/editions/:

Profile	Use case
oss.env.example	Minimal local — SQLite, no Redis
oss.local-power.env.example	SQLite + Redis exact cache
oss.team.env.example	Postgres + Redis + Qdrant — full team deployment

Every environment variable is listed in documentation/ENVIRONMENT.md.

CLI

Build from source (go build -o aurora ./apps/aurora) and run directly:

Command	Description
aurora	Start the gateway server (default port 8080)
aurora init	Scaffold config.yaml, .env, data/
aurora bindproxy	Run a single-IP HTTP CONNECT proxy (started automatically per egress IP)
aurora models sync	Download upstream model registry to a local file
aurora models diff	Show pricing diff between upstream and local snapshot
aurora models show	Print effective pricing for a model
aurora -version / -help / -help-json	Version, help, env schema as JSON
