Developers often face a time‑consuming hurdle after coding: crafting distinct launch announcements for Reddit, Dev.to, X (formerly Twitter), and Peerlist. PromoBot addresses this by turning a project's README.md into a complete, platform‑specific marketing campaign. Leveraging Google Gemini 1.5 Flash, the tool analyses the README, generates tone‑adapted copy for each outlet, and publishes the content automatically.

For platforms lacking robust public APIs, PromoBot employs Playwright browser automation to mimic human interactions, ensuring reliable posting while avoiding bot detection. Its event‑driven, microservices‑like architecture uses Redis and Celery for asynchronous task queues, providing fault‑tolerant, concurrent execution. PostgreSQL stores campaign history, session data, and configuration, while SQLAlchemy abstracts database operations.

The Strategy Pattern enables plug‑in style extensions, allowing new platforms to be added without altering core logic. By automating the entire marketing workflow, PromoBot frees developers to focus on building, delivers consistent messaging across audiences, and scales launch efforts with minimal manual effort.
