Drop-in: OpenAI-compatible API and SDK, the flatkey CLI, or plug straight into Codex and Claude Code. Text, image, video and audio models. SOC 2 data security.
Hey Product Hunt 👋
We built flatkey because our own AI bill had turned into a mess. We had one account for Claude, another for GPT, more for Kimi, DeepSeek and GLM, plus a video model on top. Each had its own key, top-up, invoice and rate limits. Most of our time went to managing accounts instead of building.
flatkey is one key and one bill for all of them.
• One key, one bill: Claude, GPT, Kimi, DeepSeek, GLM, Seedance and more on a single balance.
• Affordable: most LLMs are 20% off official pricing.
• Same quality: you get the same output as calling the official models, and 10,000+ customers have tested that.
• Easy to switch: change base_url to router.flatkey.ai/v1 in the OpenAI SDK. You can also use the flatkey CLI, or plug it into Codex and Claude Code.
• All modalities: text, image, video and audio.
• Secure: SOC 2.
One example: VOC.ai has analyzed 1B+ Amazon reviews with ChatGPT. They moved that workload to flatkey and cut their model costs by 40%.
We'd love your feedback: which model should we add next, and what does your AI bill look like today? We'll be here all day answering questions.
