Tokenomy

Tokenomy is a developer-focused token intelligence tool for teams building with LLM APIs that need to predict token usage and costs before making API calls.

Key capabilities include:

• Real-time token and cost prediction across multiple models (including GPT-4o and Claude) to reduce billing surprises during development and testing
• IDE and workflow integrations, including a VS Code sidebar, CLI, and LangChain callback support for surfacing estimates inside existing pipelines
• Cost visibility and guidance, with token usage visualization, analysis, and cost-saving tips and alerts to help control ongoing spend

Pricing: Free to use; no credit card required.

What makes it notable is its focus on upfront cost estimation inside developer workflows, not just after-the-fact reporting, with support for common providers such as OpenAI and Anthropic.
