🧊 Open source LLM observability platform. One line of code to monitor, evaluate, and experiment. YC W23 🍓

Fastest enterprise AI gateway (50x faster than LiteLLM) with adaptive load balancer, cluster mode, guardrails, 1000+ models support & <100 µs overhead at 5k RPS.

Nadir is a Python package designed to dynamically choose the best llm for your prompt by balancing complexity and cost and response time.

One API for 25+ LLMs, OpenAI, Anthropic, Bedrock, Azure. Caching, guardrails & cost controls. Go-native LiteLLM & Kong AI Gateway alternative.

Stop overpaying to run your agents. Kalibr routes every request to lower-cost model and tool paths without degrading performance.

Cloud FinOps Agent Skill — expert guidance on AI cost management, AWS/Azure optimization, tagging governance, and FinOps framework implementation. Built by OptimNow.

Know what your AI agents cost. API gateway with budget enforcement, session tracking, and MCP tools.

An LLM Cost Calculator for all the major services

A curated list of strategies, tools, papers, and resources for reducing LLM token costs and improving efficiency in production.

Cut your OpenClaw / ZeroClaw token bill. Find which model earns its cost. Prove whether optimizations actually work. Local, no upload.

Track, visualize, and optimize LLM API spending. Monitor OpenAI & Anthropic costs per feature, detect waste, suggest savings. Zero-config Python profiler.

LLM API Cost Calculator

Your AI agents are burning money. AImeter shows you exactly how much.

Free AI API cost calculator SDK for TypeScript and Python with verified, continuously updated model pricing.

Calculate your AI agent infrastructure costs. Compare cloud-only vs hybrid local+cloud inference. Real numbers from production.

Simple tool to estimate AI API costs when using large language models.

Static cost analysis for LLM workloads. Catch budget overruns before they hit production — like Infracost, but for AI. Offline-first, single binary.

Local-first observability for Claude Code - drill into costs, prompts, and tool calls turn by turn. Zero instrumentation.

Just like synapses optimize neural transmission with precise weights, Synapse TOON optimizes your API payloads with precision encoding. 30-60% fewer tokens, neural-grade efficiency.

Governance layer for token-scoped authority and policy enforcement.
