What it does

Diffmode_free is a free Claude Code + Codex plugin that runs a real growth-strategy pipeline for bootstrapped founders, providing competitor read, buyer JTBD map, and unconventional acquisition tactics

When to use it

•When you need to quickly identify growth opportunities without extensive market research
•When you want to automate the process of analyzing competitors and buyer needs
•When you're looking for unconventional acquisition tactics to boost your startup's growth

Ready-to-paste prompt

python diffmode_free.py --competitor_example='Uber' --buyer_example='ride-hailing customers'

Heads up: Make sure you have Python installed on your local machine and Apache-2.0 license terms are understood, as the plugin uses local execution and relies on specific libraries
