This should surprise no one, but a paid Claude plan doesn't just get you limits that are a bit less brutal than the free tier. You also get access to a lot of features that Anthropic keeps behind the paywall. If you're on the free tier, or have a paid Claude account but are frustrated with just how fast you burn through your quota, the good news is that the open-source community has your back.

They've built alternatives to a lot of the paid features Anthropic offers, meaning you can get most of what you're paying for without paying for it. Or well, at least without paying Anthropic for it.

OpenCode

Claude Code without the Claude Code subscription

Long before Claude went viral and turned into the AI tool every other person defaults to, a niche community of builders and developers "gatekept it" because of how great Anthropic's models were at coding and development tasks. In addition to developers realizing that Claude models consistently produce better and more reliable code, Anthropic doubled down on that reputation by launching Claude Code in early February 2025. If you aren't familiar with the origin story of Claude Code, it began as a side project by Boris Cherny in his first month at Anthropic, where he joined after five years at Meta. After realizing he'd accidentally built something useful, Cherny shared it internally. It spread so quickly that by the time Anthropic decided to launch it publicly in May 2025, over 80% of its own engineers were already using it every day.

Fast forward to today, and Claude Code is practically synonymous with AI-assisted coding. However, the catch is that you need a paid Claude subscription to actually use Claude Code in the traditional sense. The cheapest path is the $20/month Pro plan, and most power users end up on the $100–$200/month Max tier just to keep from burning through their quota mid-task. You're also locked into Anthropic's own models (though you can find ways around it), so if you'd rather experiment with GPT, Gemini, or run something locally on your own machine, Claude Code isn't really the best tool for that.

OpenCode is. It's an open-source coding agent that does basically everything Claude Code does (editing files, running commands, refactoring across entire codebases) for free. Well, sort of. OpenCode itself is completely free and open-source, but the models it runs on aren't always. If you bring your own API key for Claude, GPT, or Gemini, you'll still pay per token on the provider's end. If you're running a model locally on your own hardware, you don't need to worry about pricing at all. The difference is that you only pay for what you actually use, instead of a flat $20–$200 every month whether you touch the tool or not.

The terminal experience holds up too. OpenCode has a clean TUI that runs in any terminal (macOS Terminal, PowerShell, whatever you use), plus a desktop app for macOS, Windows, and Linux, and a VS Code extension if you'd rather not leave your editor. It has the same Plan/Build mode split as Claude Code (Tab to switch), drag-and-drop image support, multi-session, /undo and /redo, and a /share command that turns any session into a public link. OpenCode also doesn't store your code or context anywhere, which is a nice bonus if you're working on anything privacy-sensitive — or if you just don't love the idea of your codebase living on someone else's servers.

Open Design

The design tool that won't eat your chat budget

While Claude Code's been around for a good bit now, a fairly new Anthropic product is Claude Design. It works similarly to a lot of the AI-centric design features you'll find within Figma, Canva, and Adobe products, and is meant to help you go from idea to a polished and shareable artifact without ever opening a traditional design tool. With Claude Design, you describe whatever you'd like to create and you'll watch Claude put together the design in real-time on its own canvas. You can then refine the output through chat or by making the changes yourself directly (though Claude Design will then implement the changes itself too by rewriting the underlying code that the design is built on. Every Claude Design artifact is really just code rendered as a live preview, which is part of why the tool can output to so many formats).

Claude Design is an impressive product, but other than it already being something you can technically generate within a regular Claude conversation, the product is also very heavy on limits. When it launched, Claude Design had separate usage limits that were only affected by how often you used Claude Design and what you used it for. Now, that's gone. As of late May 2026, Anthropic rolled out a change that folds Claude Design's quota into the same shared pool as Claude.ai and Claude Code, meaning every design you generate eats into the same allowance you'd otherwise spend on chatting or coding.

Well, that's where Open Design comes in. Open Design is a local-first, open-source alternative to Claude Design built by nexu-io. It's a native desktop app for macOS and Windows that uses the agent-native loop Claude Design pioneered (describe the brief, watch the artifact get built, refine it, ship it) without any of the lock-in. You can generate web, desktop, and mobile prototypes, live dashboards, slide decks, images, video, and even motion graphics, all rendered in a sandboxed preview and exportable as HTML, PDF, PPTX, or MP4 files that land directly in your project folder instead of someone else's cloud.

The cleverest part of Open Design's design (sorry) is that it doesn't ship its own agent. Instead, it uses whatever coding agent CLI you already have installed as the design engine. There are 17 first-party adapters supported out of the box, including Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot CLI, Grok, Kimi, Qwen, and yes, OpenCode, the open-source tool from the previous section. Open Design ships with over 100 composable skills (covering everything from landing pages and pitch decks to social media dashboards and waitlist pages) and 150 brand-grade design systems, including ready-made kits for brands like Claude, Cohere, ElevenLabs, Mistral, Ollama, and OpenCode itself. You can also drop a screenshot or Figma export into the web UI and ask your agent to extract a brand into a reusable DESIGN.md file.

And if you've already been using Claude Design and don't love the idea of starting from scratch, Open Design lets you import Claude Design ZIP files directly. The cost structure is the same shape as OpenCode's, too. Open Design itself is free and Apache 2.0 licensed, and you only pay for the underlying model usage through whichever provider you bring keys for. Keep in mind that Open Design does require you to install the desktop app and have at least one coding agent CLI on your system for it to work. If that setup hurdle doesn't scare you off, though, Open Design is the closest thing to a real, unrestricted Claude Design clone that currently exists.

Hermes Agent

Cowork that lives outside the Claude Desktop app

Full disclosure, I haven't had the time (or resources, thanks to my poor 8GB MacBook RAM) to spin up Hermes Agent and put it through its paces.Full disclosure, I haven't had the time (or resources, thanks to my poor 8GB MacBook RAM) to spin up Hermes Agent and put it through its paces. However, Cowork is something I've tested extensively, and Hermes Agent is an open-source AI agent folks at XDA have landed on after putting OpenClaw (the more popular open-source agent in this space, which you've certainly heard about) through tests and finding it wasn't worth the security risk. So while I can't give you a hands-on take just yet, I can tell you why it's the most credible open-source alternative to Cowork right now.

Now, if you've been following Anthropic's product launches, you've probably heard of Cowork. If you haven't, Cowork is Anthropic's desktop AI agent. It lives inside the Claude Desktop app and, with your permission, gets access to a specific folder on your machine, where it can read, create, and organize files, draft documents and spreadsheets, and automate things like browser actions and reports. It's still technically in research preview, so you can expect some rough edges, but it's already surprisingly capable for the everyday "do this admin work for me" use case.

Hermes Agent is the open-source version of that idea, except it doesn't really stop at your desktop. It's a self-hosted autonomous agent that runs on your own machine and brings its own persistent memory across sessions. It connects to messaging apps like Telegram, Discord, Slack, and WhatsApp, so you can text it anywhere. It's MIT-licensed, free forever, and you bring your own LLM keys (OpenAI, Anthropic, OpenRouter, or a self-hosted model) — so the only cost is whatever you'd be paying that provider directly. You can read more about it in this separate article XDA's own Adam Conway wrote about it!
