CRM and sales decision
Commentify
A capable developer can build a limited commenting agent (discovery, generation, scheduling, exports) with open-source building blocks, but matching Commentify's safety, voice-fine-tuning polish, scale, and analytics would require more effort and ongoing ops; keep paying for full product unless you only need a narrow workflow.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Discover ICP-relevant posts, generate contextual comments in the user's voice, schedule/post comments at human-like intervals, surface a queue for review/approval, and record engagement metrics for export.
What it still won’t have
- Enterprise polish, priority support and SLAs
- Proven safety and policy handling tuned by the vendor (sensitive-content filters, long-term safety tweaks)
- Scale-tested posting infrastructure and rate-limit management across many accounts
- Polished analytics dashboard and built-in integrations (CSV/webhook exports tuned for CRMs)
- Ongoing product improvements, A/B tests, and UX refinements
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal Commentify replacement: backend in Python (FastAPI), Postgres for state, Redis for job queue, Playwright for real-browser automation to authenticate and post to LinkedIn/X, and a React single-page app for configuring ICP filters, review queue, and basic analytics. Core features: (1) account connect via browser session capture, (2) post discovery by hashtag/profile/feed scraping with ICP filters (titles, company size, geography), (3) comment generation using OpenAI/Anthropic API with per-user fine-tuning via prompt templates and ability to upload 8 sample texts, (4) approve/edit queue and humanized scheduler with randomized intervals and retry on failure, (5) CSV export and webhook for engagements, (6) sensitive-content filter (skip politics/tragic topics). Out of scope: native mobile app, enterprise SSO, white-labeling, paid analytics beyond CSV/webhook. Include robust error handling for posting failures and rate limits, unit and integration tests for scraping, generation, scheduling, and exports, and basic CI/CD deployment scripts (Docker + single small cloud VM).
