Can an agent replace GitHub Copilot?
AI code completion and chat inside your editor.
This is the one case where the answer is circular: Copilot is an agent, and it is being replaced by better agents. The category is moving from completing your line to completing your ticket, and the pricing has not caught up with what that is worth.

- €40/mo

- from €10/user/mo
- Verdict
- The product was the labour. An agent and somewhere to put the data covers it.
What the agent takes over
Every job this product exists to perform, with our verdict on each. Follow one through for the step-by-step breakdown.
- Software developmentMostly. An agent writes, tests and ships real features in a codebase it can read, and it does so faster than a person. It cannot decide what to build, and it degrades badly as a system gets large and undocumented.MOSTLY
- Code reviewMostly, as the first pass rather than the last. An agent catches the mechanical problems reliably and never gets bored on the four hundredth PR. It cannot tell you the change is a bad idea, which is what senior review is for.MOSTLY
- DocumentationYes, and it fixes the real problem, which was never writing documentation but keeping it true. An agent regenerates docs as the code changes, which no human team has ever sustainably managed.YES
- QA testingYes. Writing tests, running regression suites, driving the browser and reporting reproducible failures is dependable agent work, and it removes the manual regression pass that everyone hates and eventually skips.YES
Why it does not survive
Distribution through GitHub. Not the capability.
What you would still need it for
- GitHub-native integration, if your workflow is entirely there
What replaces it
- A coding agent that works at ticket level rather than line level
The brief
What you would tell an agent to take over from GitHub Copilot, assembled from the jobs above.
I want to cancel GitHub Copilot. It currently does: AI code completion and chat inside your editor. Take over this work: - Software development — MOSTLY. Mostly. An agent writes, tests and ships real features in a codebase it can read, and it does so faster than a person. It cannot decide what to build, and it degrades badly as a system gets large and undocumented. - Code review — MOSTLY. Mostly, as the first pass rather than the last. An agent catches the mechanical problems reliably and never gets bored on the four hundredth PR. It cannot tell you the change is a bad idea, which is what senior review is for. - Documentation — YES. Yes, and it fixes the real problem, which was never writing documentation but keeping it true. An agent regenerates docs as the code changes, which no human team has ever sustainably managed. - QA testing — YES. Yes. Writing tests, running regression suites, driving the browser and reporting reproducible failures is dependable agent work, and it removes the manual regression pass that everyone hates and eventually skips. Do not take over: - GitHub-native integration, if your workflow is entirely there These stay with me across all of it: - What to build - Architecture decisions with long consequences - Production accountability - Code review - Approval - Architectural judgement - Deciding a change should not exist - Architectural rationale - Deciding what deserves documenting - The overall narrative - The release decision - Judging severity against business risk - Usability judgement Before we start, tell me: which of these you cannot do with the access I can actually give you, and what would break if this ran unattended for a month. — brief built at cananagentdo.com/github-copilot

Replace GitHub Copilot
That is €40 a month back, and one fewer login. The work is connecting an agent to the systems GitHub Copilot was sitting between.
