Backmesh
Open-source backend to secure and manage LLM API access
What is Backmesh? Complete Overview
Backmesh is an open-source backend solution designed to protect and manage access to LLM (Large Language Model) APIs. It provides robust security features such as JWT authentication, rate limiting, and resource access control to ensure only authorized users can interact with your LLM APIs. Backmesh is ideal for developers and enterprises looking to safeguard their API keys, prevent abuse, and maintain control over sensitive resources like files and threads. Its battle-tested architecture makes it a reliable choice for securing API endpoints while offering flexibility through self-hosting options.

What Can Backmesh Do? Key Features
JWT Authentication
Backmesh ensures secure access to your LLM APIs by verifying requests with JSON Web Tokens (JWTs) from your app's authentication provider. This guarantees that only authenticated users can make API calls, preventing unauthorized access and potential misuse of your API keys.
Rate Limits per User
With Backmesh, you can configure per-user rate limits to prevent abuse of your LLM APIs. For example, you can set a limit of 5 OpenAI API calls per user per hour, ensuring fair usage and protecting your API resources from being overwhelmed by excessive requests.
API Resource Access Control
Backmesh protects sensitive API resources such as files and threads, ensuring that only the users who create them can access or modify them. This granular control enhances security and privacy, making it ideal for applications handling user-specific data.
Open-Source & Self-Hosting
Backmesh is fully open-source, allowing developers to inspect, modify, and self-host the solution. This flexibility ensures you can tailor the backend to your specific needs while maintaining full control over your infrastructure.
Scalable Pricing
Backmesh offers a simple and predictable pricing model based on requests and monthly active users (MAUs). With options ranging from a free trial to enterprise plans, you can scale your usage as your needs grow without unexpected costs.
Best Backmesh Use Cases & Applications
