As answered by people managing Testim and 1DevTool.
1DevTool's answer:
1DevTool is the only developer workspace that combines a browser, AI prompt editor, persistent terminals, smart notifications, and activity logs in one app — and sends console errors, network requests, and screenshots to your AI agent in a single click. No copy-pasting. No tab-switching. Developers save 40+ minutes every day without changing how they work.
1DevTool's answer:
Indie developers and solo founders Freelance full-stack developers AI-assisted development teams
1DevTool's answer:
Cursor and GitHub Copilot are great AI editors — but they don't eliminate the switching between Chrome, terminal, and AI tools that kills your focus. 1DevTool does. It's also a one-time $29 payment. No monthly subscription. No vendor lock-in. You own it forever.
1DevTool's answer:
Electron, Node.js, React
1DevTool's answer:
Full-stack developers and indie hackers who use AI coding agents (Claude, Codex, Gemini) daily and are frustrated by the constant context-switching between their editor, browser, terminal, and AI chat. Especially solo developers and freelancers who want a lean, focused environment without paying for 5 separate SaaS tools every month.
1DevTool's answer:
Built by a solo indie developer who was tired of Alt-Tabbing 50 times a day just to debug one bug. The idea was simple: what if your browser, terminal, and AI assistant all lived in the same window? 1DevTool was born from that frustration — a no-nonsense workspace built for developers who want to stay in flow and ship faster.
