Free calculators and tools for automation buyers
Interactive, no-signup tools to help you size and price automation platforms.
Automation Pricing Calculator
Compare Zapier, Make, n8n, and Rills pricing for your monthly volume: cheapest plan, monthly cost, and price per task.
Automation Payback Calculator
Build vs buy vs hire: compare DIY automation, an agency build, a VA, and keeping it manual. See your break-even month and 3-year savings.
AI Agent Cost Calculator
Price an AI agent loop per run and per month across 19 models from Anthropic, OpenAI, Google, xAI, and DeepSeek, against the same job as a supervised Rills workflow.
Cron Expression Generator
Type a schedule in plain English ('weekdays at noon') and get the cron expression. Paste a cron and get plain English back, with the next five run times.
JSON Schema Generator
Build a schema for LLM structured outputs visually, or paste example JSON and let the tool infer it. Copy provider-ready snippets for OpenAI, Claude, Gemini, and Zod.
Approval Gateway
Add a human approval step to any Zapier, n8n, or Make workflow. One API call creates a mobile-friendly approval link; a webhook fires when someone decides.
