## Performance at a Glance

- **11µs Gateway Overhead.** Per request at 5K RPS
- **5K Requests/Second.** Sustained throughput
- **1000+ AI Models.** Unified API access
- **0 Configuration.** Deploy in seconds

## OSS Features

- **99.999% uptime - Automatic failover:** Seamless provider switching when primary systems fail. Zero downtime when OpenAI, Anthropic, or other providers experience outages or hit rate limits.
- **Weighted routing - Intelligent load balancing:** Weighted API key distribution with model-specific filtering. Route requests across multiple keys and providers for higher throughput and reliability.
- **Cost savings - Semantic caching:** Intelligent response caching based on semantic similarity. Reduce costs and latency by serving similar queries from cache instead of hitting the model.
- **Access control - Virtual keys & budgets:** Create separate credentials for each team or project with independent rate limits and budgets. Hierarchical cost management across virtual keys, teams, users, and customers.
- **OTEL native - Real-time observability:** Built-in request tracking, performance analysis, Prometheus metrics, and OpenTelemetry integration. Monitor every AI request in real-time.
- **Zero refactor - Drop-in replacement:** Replace existing AI SDK connections by changing just the base URL. Works with OpenAI SDK, Anthropic SDK, LangChain, and all major frameworks.

## Why Startups Choose Bifrost OSS

- **Zero cost to start:** Free, open-source, and production-ready. No enterprise license required for core functionality. Deploy on your infrastructure and scale without vendor lock-in.
- **Scale without breaking:** Built in Go for high-performance workloads. Handles 5,000 requests per second with only 11µs overhead. Scales horizontally as your startup grows.
- **Avoid provider lock-in:** Switch between 1000+ models without code changes. Compare model quality, cost, and latency across OpenAI, Anthropic, Google, and others from day one.
- **Cut costs immediately:** Semantic caching reduces redundant model calls. Load balancing optimizes API key usage. Virtual key budgets prevent runaway spending.
- **Ship faster:** No need to build custom routing, failover, or monitoring infrastructure. Focus on product features while Bifrost handles LLM reliability and observability.
- **Community-driven:** Open source with active GitHub community. Contribute features, report issues, and learn from other startups building with Bifrost.

## Core Capabilities

- **Multi-provider routing:** Direct requests to specific models and providers with weighted strategies. Support for OpenAI, Anthropic, AWS Bedrock, Google Vertex, Azure, Groq, Mistral, Cohere, and 12+ additional providers.

## OSS vs Enterprise

OSS provides production-ready core features. Enterprise adds compliance, advanced governance, and priority support.

| Category | Open Source (Free) | Enterprise |
| --- | --- | --- |
| Core Features | Automatic failover; Load balancing; Semantic caching; Virtual keys & budgets; 1000+ models support; MCP tool filtering | Everything in OSS; Adaptive load balancing; Advanced routing strategies; Adaptive multi-region failover |
| Observability | Real-time request logs; Prometheus metrics; OpenTelemetry integration; Built-in web UI; Cost tracking | Everything in OSS; Datadog/BigQuery connector; Log exports; Audit logging; Compliance reports |
| Security & Governance | Virtual key access control; Rate limiting; Budget enforcement; MCP tool permissions | Everything in OSS; Guardrails (PII, content moderation); SSO (like Okta, Entra); RBAC; Vault integration; In-VPC deployment |
| Extensibility | Go plugins; WASM plugins; Mocker plugin; Custom plugins | Everything in OSS; Priority support |

## Use Cases

- **Early-stage startups:** Launch AI features without infrastructure overhead. Free OSS provides production-ready failover, caching, and multi-provider access from day one.
- **Rapid prototyping:** Test models across OpenAI, Anthropic, Google, and others without large code changes. Compare quality and cost before committing to one provider.
- **Cost-conscious teams:** Semantic caching and load balancing reduce redundant LLM spend. Virtual key budgets prevent surprise bills. Free OSS means no gateway license fees.
- **SME AI adoption:** Small and medium enterprises can deploy enterprise-grade LLM infrastructure without enterprise budgets. Self-host on existing infrastructure.
- **Developer tools:** Integrate AI features into developer tools, IDEs, or CLI applications. Go SDK provides direct embedding. HTTP gateway works with any language.
- **Open source projects:** Add AI capabilities to open source software without vendor dependencies. Community-driven development with transparent roadmap and governance.

## FAQ

### Is Bifrost OSS truly free for production use?

Yes. Bifrost OSS is Apache 2.0 licensed and includes production-ready features like automatic failover, load balancing, semantic caching, and multi-provider routing at zero cost. No enterprise license required for core functionality.

### What are the limitations of the OSS version?

OSS includes all core LLM gateway features. Enterprise adds advanced governance (guardrails, RBAC, SSO), compliance features (audit logging, in-VPC deployment), and priority support. Most startups and SMEs find OSS sufficient for production workloads.

### Can I self-host Bifrost OSS on my infrastructure?

Yes. Bifrost OSS deploys via Docker, Kubernetes (Helm), standalone binary, or embedded Go SDK. Self-host on AWS, GCP, Azure, or any infrastructure. No data leaves your environment unless routing to external LLM providers.

### How does Bifrost OSS compare to hosted LLM gateways?

Bifrost OSS is self-hosted (zero gateway fees), open source (full transparency), and community-driven. Hosted alternatives like Helicone or Portkey charge per request or require enterprise contracts. OSS gives you control and flexibility.

### Does OSS include the web UI and monitoring dashboard?

Yes. The built-in web UI provides visual configuration, real-time request logs, cost tracking, and performance analysis. Prometheus metrics and OpenTelemetry integration are also included in OSS.

### When should I upgrade from OSS to Enterprise?

Upgrade to Enterprise when you need compliance features (SOC 2 Type II, HIPAA, GDPR), advanced security (guardrails, SSO, RBAC), audit logging for regulated industries, or in-VPC deployment with priority support. OSS is production-ready for most use cases. Get 14 days free enterprise trial. [Get 14 days free enterprise trial](https://www.getmaxim.ai/bifrost/enterprise).
