Token saver
Self-hosted caching proxy that cuts LLM API costs
TokenSaver is a self-hosted caching proxy that sits between your app and the LLM API. It deduplicates prompts using SHA256 for exact matches and sentence-transformers embeddings for near-identical queries. Catch retries, refreshes, and the same question from different users before they reach the API. Includes per-user budgets, Slack/email alerts, rate limiting, per-model cost analytics, and anomaly detection. Free for up to 5 users (MIT).
Hey ProductHunt! I built TokenSaver because my team was paying for the same GPT-4o calls 3-4 times without realizing it.
The key insight: most teams send the same prompts repeatedly — retries after timeouts, multiple devs building the same feature, dashboard refreshes. A SHA256 cache catches exact duplicates. A semantic embedding cache catches near-identical queries.
It's self-hosted with Docker, works with any OpenAI-compatible client. Free for small teams (MIT license).
Built solo from Mumbai, India. Would love your feedback!
