Point your existing OpenAI client at one endpoint and reach OpenAI, Anthropic, and more. Switch models by changing a single string - with automatic routing, failover, and one prepaid bill. Today the gateway routes 85 models across 23 providers behind a single endpoint. Full privacy - developed & hosted in Switzerland
Crow framework boldrouterboldrouter's answer:
boldrouter is a Swiss-hosted unified LLM gateway that gives developers and businesses access to leading AI models through a single API key and an OpenAI-compatible interface. Its distinctive combination of multi-provider access, smart routing, automatic failover, centralized billing, token-accurate metering, scoped API keys, usage analytics, and enterprise controls allows teams to use multiple AI providers without rebuilding their applications for each one.
boldrouter's answer:
boldrouter is designed for teams that want simplicity without being locked into a single AI provider. Developers can keep using familiar OpenAI-compatible SDKs while accessing models from OpenAI, Anthropic, Google, xAI, DeepSeek, Perplexity, Mistral, Z.ai, and others. Centralized routing, failover, usage tracking, billing, and API-key management reduce the infrastructure that teams otherwise need to build and maintain themselves. Its Swiss-hosted infrastructure is also particularly attractive to European and privacy-conscious organizations.
boldrouter's answer:
No major external customers have been publicly disclosed yet. boldrouter launched its public beta on July 21, 2026, so publicly announced customer references are still limited.
boldrouter's answer:
boldrouter is primarily built for software developers, AI startups, SaaS companies, engineering teams, platform teams, and enterprises building applications with large language models. It is especially useful for organizations that use, test, or compare multiple AI providers and want one centralized API, billing system, routing layer, and usage dashboard instead of managing separate integrations for every provider.
boldrouter's answer:
The platform incorporates multi-model routing, automatic failover, token metering, scoped API-key management, usage analytics, centralized billing, and Swiss-hosted cloud infrastructure. The underlying programming languages and internal framework stack have not been publicly disclosed.
boldrouter's answer:
boldrouter was created by Swiss technology group Cybrient Technologies SA to simplify the increasingly fragmented LLM ecosystem. As companies began using models from multiple AI providers, managing separate APIs, credentials, billing systems, monitoring, and failover logic became increasingly complex. boldrouter was built as a unified layer between applications and AI providers, allowing developers to integrate once and then choose or switch between models as their requirements evolve. The platform officially launched its public beta on July 21, 2026 in Zรผrich, Switzerland.

I did something similar in the past and used https://github.com/ipkn/crow as web server, in case you want to not implement the web part yourself. Otherwise amazing job! Source: over 3 years ago

Last year I was looking to port a Flask REST API I made to C++ because speed and why not. I went through a few C++ frameworks but eventually chose the abandoned since 2017 Crow. It was by far the easiest to set up and work with (being inspired by Flask in the first place), and it didn't hurt that it supported Websockets. Source: about 5 years ago
