Bifrost (Maxim)

Overview

Bifrost is a high-performance, Go-based LLM gateway designed for cost governance and access control. It provides a unified API surface to manage and route requests across 1000+ language models while maintaining centralized control over costs, permissions, and performance. Available as both open-source software and an enterprise solution, Bifrost serves as a drop-in replacement for existing AI SDK connections.

Key Features

Gateway & Routing

• Single OpenAI-compatible API to unify access across multiple models and providers
• Drop-in replacement capability by changing the base URL
• Custom routing rules and flows for intelligent request distribution
• Automatic fallbacks for seamless failover between providers and models

Cost Control & Governance

• Hierarchical budget management and rate limiting across virtual keys, teams, and customers
• Virtual keys for granular control over access permissions, budgets, and routing per consumer
• Real-time budget alerts and notifications via Email, Slack, PagerDuty, Teams, and webhooks

Observability & Monitoring

• Built-in observability dashboard for monitoring every AI request in real time
• OpenTelemetry (OTEL) compatible metrics and traces
• Native Prometheus monitoring and alerting support
• HTTP-level and upstream provider metrics
• Optional Maxim AI integration for advanced LLM observability and evaluation

Performance & Reliability

• Adaptive load balancing that optimizes traffic distribution based on real-time performance metrics
• Semantic caching to reduce costs and latency for similar queries
• Simple and semantic caching options
• Async inference for submitting requests asynchronously and polling for results

Advanced Capabilities

• MCP (Model Context Protocol) gateway with code mode and federated authentication
• Prompt repository and playground for creating, testing, and versioning prompts
• Bifrost CLI for governing coding agents like Claude Code and Gemini CLI
• Custom plugin development support (Go or WASM)
• Guardrails for real-time content safety and policy enforcement

Enterprise Security

• Enterprise SSO via SAML and OIDC
• Role-based access control (RBAC)
• Vault support with integrations (HashiCorp Vault, AWS Secrets Manager, Google Secret Manager, Azure Key Vault)
• VPC deployment options for private cloud infrastructure
• Audit logs and comprehensive logging for compliance
• Air-gapped, on-premises, and hybrid deployment support

Use Cases

• Cost Optimization: Centralize LLM spending across teams and customers with hierarchical budget controls
• Multi-Model Management: Route requests intelligently across multiple providers and models from a single API
• Enterprise Compliance: Enforce security policies, audit trails, and access controls at scale
• High-Availability Systems: Deploy production AI systems with clustering, failover, and load balancing
• Development & Testing: Use the mocker plugin and prompt repository for testing and simulation
• Agent Governance: Control access and routing for AI coding agents and autonomous systems
