24 alternatives to Duende: Web UX for guiding Gemini as it improves your source code
I wrote a simple web UX in Python/JavaScript that spawns a conversation with Google Gemini with MCP commands that let it work on a specific coding task that you specify: http://github.com/alefore/duende The UX lets you observe the conversation and provide guidance (e.g. "don't implement Foo through Bar, that's suboptimal; instead …"). It supports a `--review` mode, where once the main conversation says "I'm done with the task", various "evaluation" conversations are spawned, each focusing on reviewing the change from a very specific angle (e.g. "does it introduce…

Gemini CLI▲224A simple weekend project, to check if chat conversation could be used on CLI. Uses Google Gemini's gemini-2.0-flash model. Configs will make it nicer, but I wanted to keep it simple to test and launch for now. I can add things for you :) Please give it a try!

I built this yesterday to help understand papers I'm interested in. It's using the gemini 2.5 flash lite model, but you can run it yourself[1] and switch to 2.5 pro for better results. Happy to answer any questions or take suggestions on how I can improve it! 1. https://github.com/montanaflynn/asxiv

The Ultimate Open Source Library for Gemini & Nano

Chrome now includes a native on-device LLM (Gemini Nano) starting in version 138. I've been building with it since it was in origin trials, it's powerful but the official Prompt API is still a bit awkward: - Enforces sessions even for basic usage - Requires user-triggered downloads - Lacks type safety or structured error handling So I open-sourced a small TypeScript wrapper I originally built for other projects to smooth over the rough edges: github: https://github.com/kstonekuan/simple-chromium-ai npm: https://www.npmjs.com/package/simple-chromium-ai…

Best to just try it :) The tl:dr is it helps you to r The summaries with references to parts of the page are useful now - and the "text zoom" tool a glimpse of where we can go Works with local Ollama and the usual suspects: Mistral/OpenAI/Gemini Obviously could be better - and hopefully will be :)

Hey HN! Thank you for all the support and feedback on my original submission 2 months ago. I've been improving the backend using a MCTS/AlphaZero approach and it's currently producing much better results. My long term goal is to allow users to manage multiple projects, deployed autonomously, both from scratch and by making continual updates all prompted with natural language. The cost of each project has been lowered to $9 as performance with smaller models has improved (I migrated from Claude-3-Opus to gemini-1.5-flash). Thanks for checking it out!

I kept running into this annoying problem: I’d remember a really useful answer, but not where it was. ChatGPT? Claude? Gemini? No idea. So I’d end up digging through all of them or just rewriting the prompt. Built this to fix that. It’s a Chrome extension that indexes chats locally and lets you search across them all in one place. Once it’s indexed, search is basically instant. Still early. UIs change and break things sometimes, so it’s a bit fragile in places. Curious if other people have the same issue or if it’s just me jumping between tools too much.

When I heard about Google's clone of Claude Code this morning I tried out my 2 week old MCP server and instantly had two way voice conversation with it. Gemini seemed a bit confused by this. :-) https://youtu.be/HC6BGxjCVnM?feature=shared&t=36 It's a FOSS MCP server I created a couple of weeks ago: - https://getvoicemode.com - https://github.com/mbailey/voicemode # Installation (~/.gemini/settings.json) { "theme": "Dracula", "selectedAuthType": "oauth-personal", "mcpServers": { "voice-mode": { "command": "uvx", "args": [ "voice-mode" ] }…

I was inspired by the notification summaries on iOS 18 and really liked the idea of AI giving you a quick preview of the content before going to the content. I applied that to HN and built a Chrome extension that summarizes the sentiment and content of HN comments and previews it right next to the stories on the homepage. Makes it so much easier to decide whether I want to delve into the HN comments of a story. It gave me a chance to play with Gemini 1.5 Flash-8B which has been great. Super fast, super cheap, huge context and does a great john on basic tasks like summarizing comment threads.…

Fun little project, had Gemini 2.5 Pro summarize HN's top 30 each hour, both the stories and comment sections. Pretty impressed with Gemini 2.5. It's probably the first model other than Claude 3.7 Sonnet where I actually find the output readable. I normally use 3.7 Sonnet for coding, but used Gemini for the codegen on this one as well. Was pretty impressed! Using Cursor, it seemed to instruction-follow better than Claude generally does, and remain lucid during very long agent sessions. Thanks for your feedback!

I built a small Chrome extension for people who write long conversations in Claude and don’t want to unexpectedly hit the 200,000-token limit. Context Compass automatically counts words and estimates token usage as you write. It updates in real time, gives you a visible percentage bar, and helps power users manage sprawling chats without losing work or flow. I built it because I kept getting the “max context” error and realized there was no way to track usage in Claude. No signups, no tracking, just a simple install. Would love any feedback or ideas for improvements. Thanks!

I built a plugin that lets Claude Code delegate work to Gemini CLI. I started this after finding myself reaching for Gemini more often on long context repo work. I have been especially liking Gemini’s codebaseinvestigator for long context. This is inspired by openai/codex-plugin-cc. Code Review, adversarial review. Under the hood its Gemini CLI over ACP Would love feedback from people using Claude Code, Gemini CLI, or ACP. I am especially curious whether this feels useful outside my own workflow. Its a great combo with Opus 4.7 + Gemini 3.1 workflows
