Claude Code: Rate limits, pricing, and alternatives

Claude Code, a coding assistant from Anthropic, is known for its powerful capabilities but is limited by cost and rate constraints, making it challenging for high-throughput applications. The new pricing structure and rate limits imposed by Anthropic have resulted in increased costs and unpredictable throttling for developers, particularly those needing stable and fast LLM-generated code. These constraints highlight issues with closed model ecosystems, including lack of control and potential security concerns. An alternative to dealing with these limitations is self-hosting open-source models on platforms like Northflank, which offers the ability to deploy models such as Qwen3 and DeepSeek without rate limits, providing full control over performance and reducing costs. Northflank supports a variety of AI models and offers flexible deployment options, allowing users to select specific models, deployment methods, and GPU resources to suit their needs, thus offering a customizable and cost-effective solution for developers seeking to avoid the constraints of closed-source AI models.
