  • Best Vibe Coding Tools for SaaS in 2026
    Google launched Gemini CLI on June 25, 2025 under the Apache 2.0 license (Google 2025). It's the only fully open-source option in this group, with a 1M-token context via Gemini 2.5 Pro and a personal-account free tier of 60 requests per minute and 1,000 requests per day. The GitHub repo at google-gemini/gemini-cli is active; GitHub Actions integration landed in late 2025. - Source: dev.to / 4 months ago
  • Gemini CLI will stop working from June 18, 2026
    Gemini CLI was open source (Apache 2): https://github.com/google-gemini/gemini-cli Antigravity CLI is not - the repo has a README and an animated gif demo: https://github.com/google-antigravity/antigravity-cli. - Source: Hacker News / 4 months ago
  • Claude Code's source code has been leaked via a map file in their NPM registry
    Is https://github.com/google-gemini/gemini-cli not 'the flagship agent' itself? It looks that way to me, for example here's a part of the prompt https://github.com/google-gemini/gemini-cli/blob/e293424bb4973fc2a281f67c43594222263b240a/packages/core/src/prompts/snippets.ts#L178-L250. - Source: Hacker News / 5 months ago
  • Is WordPress dead? (Or just too stubborn to notice?)
    We now have AI coding tools — Claude Code, OpenAI Codex, Google Gemini CLI — that can generate a complete, production-ready website from a conversation. Not a template. Not a wireframe. An actual, deployable site. - Source: dev.to / 5 months ago
  • Making Sure Your Prompt Will Be There For You When You Need It
    Trying to make samples in large batches is different from asking for a single sample from a tool like Gemini CLI. When producing many samples at once, we see more mistakes because the statistics catch up with us. A small percentage of bad samples becomes a large number once the overall number of samples gets higher, not unlike issues in manufacturing. Here are some examples of mistakes. - Source: dev.to / 6 months ago
