GitHub Copilot

The most widely deployed coding assistant, available in most major editors.

Copilot works as an extension inside VS Code, JetBrains IDEs, Neovim and others, which means you keep your existing setup. It offers inline completion, a chat panel, and code review on pull requests. Its reach is the main selling point: it is the assistant most likely to be already approved by your employer.

Copilot is usually not a decision so much as something already installed — it came with the organisation's GitHub plan. That changes the useful question from whether to adopt it to what to still reach for elsewhere. Its completion layer is mature and nearly frictionless; its agent layer is newer and competes with tools built agent-first. Teams that are happy here are generally using it for the thing it has always been good at, and keeping a separate tool for long autonomous runs.

Our take

The safe institutional choice rather than the most capable one. It lives inside the editor you already use, it is the tool corporate security teams have most often already approved, and it does the everyday job — finishing the line, filling in the obvious — without asking you to change anything about how you work. Where it is behind is agentic, repository-wide work, which is exactly where the newer entrants concentrate.

Best for

Adding AI assistance without changing your editor
Organisations that need a vendor their security team already accepts
Boilerplate, tests and repetitive code you can verify at a glance

Limitations

Weaker repository-wide context than editor-native competitors
Suggestion quality drops in less common languages and frameworks
Confident completions in unfamiliar territory are easy to accept without checking

When to pick something else

Large multi-file refactors, where an agent-first tool does more
Codebases that cannot be sent to a third-party service

Key features

Works inside your existing editor, no migration needed
Inline completion plus chat in the same extension
Pull request review and summaries on GitHub
