Free tools for founders, freelancers & devs.
Browser-first utilities that do one thing well — invoicing, task tracking, prioritisation, focus, AI interview prep, screen recording, markdown, growth. Built by Codersera so you don't have to deal with email gates, watermarks, or "free trial" pop-ups.
Use these tools from ChatGPT, Claude, Cursor or Codex
One endpoint connects your AI agent to Domain Rating checks, IP lookups, invoices, notes, tasks, and the directory list — no tab-switching.
