If you have been following the AI coding assistant space, you have probably noticed something interesting happening in 2026: the shift from IDE plugins to terminal-native tools. We covered the broader landscape in our AI Coding Assistants comparison, and Claude Code has emerged as one of the most talked-about options. Claude Code, Anthropic’s agentic coding assistant, has been at the centre of this change — and version 2.1.121, released today (April 28), brings another wave of improvements that make it worth a closer look.

Whether you are a solo developer looking to speed up your workflow or a team evaluating AI tools, here is what Claude Code is, what the latest update adds, and whether it makes sense for your stack.

The Problem: AI Assistants That Only Work Inside an IDE

Most developers who have tried AI coding tools are familiar with the pattern: you install an extension in VS Code or JetBrains, start typing, and the AI suggests the next few lines. It works well enough for simple completions, but for anything more complex — refactoring across multiple files, debugging a tricky issue, writing tests for an entire module — the context is too narrow. You end up copying and pasting between your editor and a chat window.

Claude Code takes a different approach. Instead of living inside an IDE, it runs directly in your terminal. It can read your entire codebase, edit files, run commands, manage git workflows, and even create pull requests — all through natural language conversation.

The result is a workflow that feels less like having an autocomplete helper and more like having a junior developer who can work independently while you focus on higher-level decisions.

What Is Claude Code?

Claude Code is an agentic coding tool developed by Anthropic. It runs as a command-line application that connects to Anthropic’s language models (including the latest Opus 4.7) to understand and modify your codebase through natural language commands.

Think of it as a coding assistant that works the way a senior developer would: it reads the full project context, proposes changes, runs tests to verify them, and adjusts based on results. It handles everything from generating boilerplate code to refactoring large sections of an existing project.

Claude Code is open-source under a permissive license and is available on GitHub (github.com/anthropics/claude-code) with over 118,000 stars. It supports Linux, macOS, and Windows through native binaries — no Node.js required for the recommended installation method.

What’s New in v2.1.121

Version 2.1.121, released April 28, is the latest in an exceptionally rapid release cadence — Claude Code has shipped 18 versions in April alone. Here are the most notable changes:

MCP alwaysLoad Option

MCP (Model Context Protocol) servers can now be configured with the alwaysLoad option. When set, tools from that server are always available without the tool-searching deferral step. This is a workflow improvement if you rely on specific MCP servers and want them ready immediately in every session.

Plugin Pruning

The new claude plugin prune command removes orphaned auto-installed plugin dependencies. If you have experimented with plugins from the marketplace, this keeps your environment clean without manual cleanup work.

Scrollable Dialogs and Terminal Improvements

Dialogs that overflow the terminal are now scrollable with arrow keys, PgUp/PgDn, Home/End, and the mouse wheel. Fullscreen mode no longer jumps the scroll position back to the bottom when you type after scrolling up. Long wrapped URLs can be opened by clicking any line of the URL, not just the last one.

Memory Leak Fixes

This is arguably the most important fix in the release. Previous versions could leak multiple gigabytes of RSS when processing large numbers of images or using /usage on large transcript histories. Version 2.1.121 resolves unbounded memory growth in both cases. If you run Claude Code in long-lived sessions — typical for VPS-based development — this fix makes a noticeable difference in stability.

MCP Auto-Retry

MCP servers with transient startup errors now retry automatically up to three times. If you use external MCP servers that occasionally fail to start on first try (for example, during a network hiccup), this reduces manual intervention.

Additional Fixes

The release also fixes a Bash tool crash when the startup directory is deleted mid-session, --resume crashing on large sessions with corrupted transcript lines, scrollback duplication on Ctrl+L in tmux, GNOME Terminal, Windows Terminal, and Konsole, and NO_PROXY not being respected for all HTTP clients.

How It Works

Claude Code uses a session-based architecture. When you start a session in your project directory, the tool indexes your codebase and maintains a working context. You interact through natural language, slash commands, or by describing tasks:

  • Natural language: “Find all places where we handle authentication and extract them into a middleware file.”
  • Slash commands: /review (analyze recent changes), /plan (outline an approach before coding), /ultrareview (deep analysis), /doctor (diagnose issues)
  • Auto mode: Claude Code executes multi-step plans autonomously, editing files, running tests, and iterating until a task is complete.

The AI inference happens entirely on Anthropic’s servers. The client itself is lightweight — it sends your code context to the API and applies the results locally. This means no GPU is needed to run Claude Code. A standard VPS with 2 GB of RAM is enough for the client, and you only pay for the Anthropic API usage.

Claude Code supports MCP (Model Context Protocol) for connecting to external tools — databases, APIs, documentation sources, or custom scripts. This extensibility means it can interact with your broader development ecosystem beyond just your source code.

When You Need It — and When You Don’t

Claude Code is not the right tool for every developer or every project. Here is an honest assessment of where it shines and where something simpler might suffice:

Claude Code is a great fit if:

  • You work primarily in the terminal and prefer CLI workflows
  • You manage complex codebases with cross-file dependencies
  • You handle repetitive tasks like writing tests, documentation, or boilerplate code
  • You want AI integration in your CI/CD pipeline (code review automation, PR creation)
  • You need persistent, long-running development sessions on a remote server or VPS

Consider a simpler tool if:

  • You only need inline code completion while typing (GitHub Copilot or Continue.dev may be a better fit)
  • You prefer a GUI-first experience with visual diffs and integrated debugging (Cursor or Windsurf)
  • You are new to coding and need in-IDE guidance rather than terminal-based assistance
  • Your codebase is very small and a chat-based tool like ChatGPT or Claude.ai handles it fine

The key distinction is autonomy. Claude Code is designed to do things in your codebase, not just suggest them. If you want that kind of deep integration and trust it with your repository, the terminal-native approach is powerful. If you prefer reviewing suggestions before applying them, many IDE plugins offer a more controlled workflow.

Getting Started with Claude Code

Installing Claude Code on a Linux server is straightforward. The recommended method uses the official install script, which downloads a native binary — no Node.js, Python, or other runtime required:

curl -fsSL https://claude.ai/install.sh | bash

Once installed, authenticate and start a session in your project directory:

claude
# Follow the OAuth prompt to authenticate with your Anthropic account

You can also install via Homebrew on macOS and Linux, or through package managers like apt (Ubuntu/Debian), dnf (Fedora), or apk (Alpine) by adding Anthropic’s official repositories.

Because Claude Code is a lightweight CLI client with no GPU requirement, it runs comfortably on a Cloud VPS from Canadian Web Hosting. A 2 GB VPS is plenty for the client itself, and using a remote server means you can leave long-running development sessions active, access them from anywhere via claude --teleport, and integrate Claude Code directly into your deployment and CI/CD workflows. For teams that want shared development infrastructure, our Enterprise Cloud platform provides the reliability and performance needed for multi-developer AI workflows.

How Claude Code Compares to Alternatives
