## VS Code

VS Code has grown from a lightweight code editor into a full development surface that spans hand-written code and delegated agent work. The core promise is unchanged: rich language support, precise navigation, an integrated debugger and terminal, and a source control view that keeps you in flow. What is new is the AI layer on top. Agents understand your codebase, work through a plan with you, apply changes across files, and present results for review rather than silently rewriting your project. A dedicated Agents window coordinates several agents running in parallel so you can move a backlog forward while you work on something else.

Under the hood, VS Code is deliberately open about how you build with AI. You are not locked to one vendor: you can choose models from Anthropic, OpenAI, Google or Microsoft, use open-weight models, or bring your own API key from another provider. You also choose the agent harness, whether that is Copilot, Claude or Codex. Model Context Protocol servers and the MCP registry extend what agents can reach, while custom agents, skills, instructions and hooks let teams encode their own conventions. Permissions, approvals and agent sandboxing give you control over what an agent is allowed to run.

Because AI features such as inline suggestions, chat and agent sessions are delivered through a GitHub Copilot subscription, the practical cost depends on your plan and how heavily you use agents. The editor, extensions, remote development support, terminal, debugging and Git integration remain free. With thousands of Marketplace extensions, accessibility features like screen reader support and high contrast themes, and a long track record of open development on GitHub, VS Code suits solo developers, small teams and large enterprises alike.

**Pricing & Plans:** VS Code itself is free and open source on all supported platforms. The built-in AI features — inline suggestions, chat and agent sessions — are delivered through a GitHub Copilot subscription: a limited free tier for occasional use, plus paid individual and business plans for higher usage, premium models and team controls. Marketplace extensions are mostly free, though some add their own paid tiers.

- **Agent collaboration and orchestration:** Agents open the repository, form a plan, edit multiple files and explain the changes so you can review each diff before accepting it. You can also run several agents in parallel to push a backlog forward.
- **Model and harness choice:** Point the editor at Anthropic, OpenAI, Google, Microsoft or open-weight models, or bring your own key. Pick the Copilot, Claude or Codex harness that matches how you like to work.
- **Deep language support:** JavaScript, TypeScript, HTML and CSS work out of the box, and Marketplace extensions add IntelliSense, linting, refactoring and debuggers for Python, Java, C++, Go, Rust and more.
- **Full development workflow:** Integrated terminal, source control, debugger, testing, Jupyter notebooks, an integrated browser and Dev Containers all live in one window, so you stay close to the code.
- **Continuity across surfaces:** Start a task locally, answer an agent's question from GitHub Mobile, redirect it in the Copilot CLI and let teammates review the pull request on GitHub.com. Settings Sync keeps everything aligned.
- **Open, extensible and everywhere:** Run the editor on Windows, macOS or Linux, in the browser at vscode.dev, inside a container, over SSH or WSL, and reach agents on your machine through Dev Tunnels.

**Strengths:** Free, open-source editor with a mature extension ecosystem and years of active development; AI agents work directly on your real codebase with plans, diffs and reviewable changes; Freedom to mix models from Anthropic, OpenAI, Google, Microsoft or open-weight providers, and to pick the Copilot, Claude or Codex harness; One setup covers local development, containers, SSH, WSL, remote tunnels and browser-based editing

**Limitations:** AI agent and chat features require a paid GitHub Copilot plan, and heavier agent workflows consume premium request quotas quickly; The full agent feature set spans VS Code, the Copilot CLI, GitHub Mobile and GitHub.com, which can feel fragmented while the ecosystem matures; Extensions run with editor privileges, so a poorly maintained or malicious add-on can pose a supply-chain risk; Large workspaces with many extensions and language servers can get memory-hungry and slow on modest hardware

## What the Diff

What the Diff plugs into GitHub or GitLab and works where developers already are. When you open a pull request, it reads the diff through the provider API and generates a descriptive comment explaining what changed, why it likely changed, and what reviewers should pay attention to. The result is a first draft of PR context that a reviewer would otherwise have to reconstruct by reading the patch.

Beyond PR descriptions, the product covers summary notifications pushed to Slack, email, or webhooks so non-technical teammates stay informed, weekly reports that aggregate a team's progress, inline refactoring where you can request improvements in a comment and let the AI draft the change, and public changelogs that can be published or pulled into other tools through a JSON API. Granular controls let you choose repositories, skip CI pull requests, delay drafts, and manage token usage.

What the Diff is built by Beyond Code and follows a token-based usage model: each diff consumes tokens, with an average pull request costing roughly 2,300 tokens. The company states that it does not store your code, that third-party services do not store it either, and that your code is never used to train models. Unused tokens do not roll over between billing cycles.

**Pricing & Plans:** What the Diff is freemium. The Free plan costs $0 per month and includes 25,000 tokens (about 10 pull requests) with unlimited repositories, automated PR descriptions, and inline refactoring. Pro starts at $19 per month for 200,000 tokens (about 40 pull requests) and scales through 500k, 1.5M, and unlimited tiers, adding Slack, webhook, and email notifications plus priority email support. No credit card is required to start, and plans do not upgrade automatically.

- **Automatic pull request descriptions:** Every PR gets a written summary of what changed in plain English, giving reviewers context without digging through the patch.
- **Summary notifications:** Simplified, translated summaries go out via Slack, email, or webhooks to keep non-technical teammates in the loop.
- **Inline AI refactoring:** Request improvements directly in a pull request comment and let the AI help draft the refactoring.
- **Weekly team reports:** Aggregate a week of work into a single clear update so nobody has to chase progress manually.
- **Public changelogs and JSON API:** Publish a public record of what is new, or pull the changelog into your own tools through a JSON API.

**Strengths:** Works inside GitHub and GitLab with no new workflow to learn; Produces genuinely useful plain-English context for non-technical readers; Free tier with unlimited repositories covers light individual use; States clearly that your code is not stored or used for model training

**Limitations:** Token-based usage can be hard to predict for teams with large diffs; Unused tokens do not roll over between billing cycles; Requires full repository access because GitHub and GitLab lack a diff-only permission
