The first decision is now maintenance ownership. Before comparing completion quality or subscription cost, check whether the tool you plan to adopt is still maintained and who will patch it if an editor or provider API changes.
This documentation comparison does not report an independent coding benchmark. It preserves the original comparison URL but updates a recommendation that previously relied on stale feature differences and unsupported savings.
The maintenance notice changes the choice
As checked on October 20, 2026, the Continue repository README says the repository is no longer actively maintained and is read-only. It describes a final 2.0.0 release of the editor integrations and CLI and identifies the project license as Apache 2.0.
That does not mean an installed copy immediately stops working. It means the earlier assumption of an actively maintained alternative is no longer suitable for a new adoption decision. An existing deployment needs an owner for security fixes, dependency changes and compatibility testing.
The source remains useful for inspection and permitted modification under its license. Open source availability and active maintenance are separate properties. Do not treat a community fork as equivalent without checking its release history, maintainers and update mechanism.
Correct the feature comparison
| Decision area | Continue installation | GitHub Copilot |
|---|---|---|
| Maintenance | Upstream README now declares maintenance ended | Check supported client and enterprise policies |
| Model configuration | Provider and model configuration in Continue’s docs | Multiple supported model providers and availability by client/plan |
| MCP | Depends on installed client/configuration | Supported in documented VS Code workflows |
| Source access | Open repository under its stated license | Product service with published documentation and policies |
| Operating cost | Model use, infrastructure and maintenance ownership | Plan charges, usage and administration |
Continue’s configuration reference documents model/provider setup. Copilot’s supported-model list is not limited to OpenAI, and VS Code supports MCP servers. The old comparison table incorrectly claimed otherwise.
Check Copilot plan availability for the exact feature you need. Support in one client does not establish identical behavior in every editor or deployment mode.
Evaluate an existing Continue deployment
Inventory the installed extension or CLI version, model endpoints, custom rules, MCP servers and background jobs. Record which workflows still work. Preserve configuration and a reproducible dependency list before changing providers or tooling.
Run a small acceptance set: a repository question, a constrained patch, a test repair and a tool call that requires permission. Compare the same starting commit and prompt across tools. Check resulting diffs and tests rather than whether the agent sounded confident.
Keep authentication and instruction discovery in the comparison. A migrated agent can produce correct code on a toy task yet miss a repository rule in a nested directory. If a workflow depends on a custom provider, test it explicitly instead of assuming a compatibility label covers every parameter.
Calculate cost without pretending maintenance is free
Use this monthly model:
total = licenses + model usage + infrastructure + maintenance hours × hourly cost + review/rework
For an illustrative maintenance scenario, allocating four hours at an assumed $50 per hour contributes $200 per month before any inference cost. This is arithmetic, not a measured Continue support burden. Use your own staffing estimate and invoices.
The earlier large-team savings figure subtracted a subscription while ignoring maintenance and operation. A fair comparison includes both and uses accepted tasks as the denominator. A lower token bill does not help if more changes need rework.
Decision and next step
For a new rollout, unresolved maintenance ownership is a reason to pause adoption of the archived upstream release. For an existing installation, a staged migration can be safer than an immediate replacement if you first record dependencies and acceptance criteria.
Keep the original tool available until the replacement passes the workflows you actually need. Do not move production credentials into a new provider merely to complete a comparison. The coding-cost guide provides a broader worksheet for separating subscription, inference and review cost.
Revision note
Updated October 20, 2026. Added the current maintenance-ended notice, removed unsupported adoption and savings figures, and corrected the false OpenAI-only/no-MCP Copilot comparison.
