bekkooazar/n8meter
A self-hosted dashboard that tells you exactly how much your n8n AI workflows cost in tokens
n8meter reads token usage from n8n workflow executions and matches it against a daily-updated catalog of over 2,500 AI model prices to calculate real costs. It shows spending broken down by workflow, client, and day, with budget alerts, all running on your own machine with no data sent to third parties. It's built for people running AI automations in n8n who have no idea what their actual API bill looks like until it arrives.
What it does
- Pulls token counts directly from n8n execution history (or via a webhook fallback for n8n Cloud's free tier, which lacks API access) and attributes usage down to the specific node and run
- Prices usage against a catalog of 2,500+ models from OpenAI, Anthropic, Google, Mistral, Bedrock and more, refreshed every 24 hours, sourced from the open LiteLLM price list
- Groups costs by workflow, client, or project, and can fire Slack-compatible webhook alerts when spending crosses a set budget (daily, weekly, or monthly)
- Runs entirely locally with data stored in a SQLite file; no telemetry or call-home, and prompts/completions are never read or stored, only token counts and costs
- Costs shown are list-price estimates for planning, not exact invoices — caching discounts and batch pricing aren't factored in, and estimated (non-provider-reported) token counts are flagged with a ≈ symbol
Why it matters
Anyone building AI workflows in n8n with multiple models and clients currently has to guess at costs until the provider bill lands, making it hard to catch runaway spending or price out client work. This gives a self-hosted, privacy-preserving way to see cost breakdowns in near real time without sending any workflow data to an external service.
