VS Code — Free code editor from Microsoft with a large extension marketplace
What it is
VS Code is a free code editor for Windows, macOS and Linux, built around IntelliSense completions, an integrated terminal and Git support. Its extension marketplace covers most languages, frameworks and tools, which makes it a common default editor for web and cloud development. Extension-heavy setups can feel heavy on memory, and some first-party features like marketplace access are tied to Microsoft's proprietary build.
Editor's review
Long-form introduction by the BetterPicker editors · checked against the official site · Oct 8, 2026
VS Code is the default code editor of the moment: free, quick to start, and extendable into nearly any language or workflow. Microsoft now positions it as the open source AI code editor, with agent modes, model choice, and a Copilot free tier that needs only a GitHub account. Official builds ship for Windows, macOS, and Linux, plus a browser version, and the current release is 1.141. The source is MIT licensed while the shipped builds carry a Microsoft license. The tradeoffs are memory appetite, settings sprawl, and a marketplace that is not open.
What it does well
The extension ecosystem is unmatched. Language servers, debuggers, theme engines, remote development, and thousands of specialist tools install in seconds, so one editor covers Python, Rust, embedded firmware, and technical books. The marketplace is the reason most new language tooling ships with VS Code support on day one.
AI assistance is built in, not bolted on. Agent mode plans and edits across files, model choice lets teams route work to different providers, and the free Copilot tier drops the entry barrier to a GitHub account. MCP servers and extension tools connect agents to databases, browsers, and the rest of a stack.
Remote and container workflows are first-class. Dev containers standardize environments in a config file, remote sessions open a server as if it were local, and the web version edits from a browser tab. For teams that fight works-on-my-machine debates, this tooling quietly ends the argument for good.
Who it's for
Students, professional developers, data scientists, and technical writers are the core audience, and it is usually the first editor installed on any new machine. It fits teams that standardize on shared profiles and extension lists so everyone's setup matches. It fits poorly for minimalists who find feature-rich editors distracting, or for air-gapped environments where a closed marketplace is a real problem.
Where it falls short
Memory and process appetite is real. The Electron core plus language servers plus a stack of extensions can consume serious RAM, and older machines feel it within an hour. Disabling unused extensions helps, but the comfort carries a resource cost that lighter editors never charge.
Settings sprawl rewards tinkerers. JSON configs, workspace overrides, and per-extension options accumulate, and a fresh install behaves very differently from one that has accreted for a year. Shared profiles tame it for teams; individuals sometimes lose an afternoon to configuration archaeology instead.
Open source with an asterisk. The source is MIT licensed, but official Microsoft builds carry a proprietary license and connect to a closed marketplace, which bothers some organizations. VSCodium and open marketplace mirrors exist as answers, with some setup friction and missing proprietary additions.

Frequently asked questions
▸What is VS Code?
VS Code is a free source code editor from Microsoft, available for Windows, macOS, Linux, and the browser. It pairs a fast editor with debugging, Git integration, an enormous extension marketplace, and built-in AI assistance through Copilot and agent modes.
▸Is VS Code open source?
Both. The source code is published under the MIT license as the Code OSS project, but the official Microsoft-branded downloads are built under a proprietary product license and connect to a closed marketplace. Open builds like VSCodium use the MIT source directly.
▸What does the free Copilot tier include?
A free tier of GitHub Copilot works inside VS Code with nothing more than a GitHub account, no trial and no card, subject to usage limits. Paid tiers raise the limits and unlock premium models and agent features for heavier use.
▸VS Code or a full IDE like JetBrains?
VS Code wins on startup speed, breadth across languages, and extension choice; JetBrains IDEs win on deep, opinionated language support and refactoring in their specialties. Many developers keep both: an IDE for the main language, VS Code for everything else.
