In one reported build, Gemini’s Antigravity workflow was smoother for getting a Dockerized app running: it checked the port and ran the deployment. Claude’s Cowork run needed the author to run Docker Compose manually, but its app included extra filters and themes. That single comparison does not show that either model is generally smarter or better at building Docker apps; the tools ran in different environments with different terminal access.
What the comparison asked the tools to build
In an article dated August 30, 2026, Dibakar Ghosh gave Claude and Gemini the same prompt for a simple, polished to-do web app. The requested deliverables included source and configuration files, a README, Docker deployment, localhost access, a check that the host port was available, data that survived container restarts, and a build and test of the app.
Ghosh describes the prompting as minimal. His report is a single project in each tool, not a repeated or independently scored benchmark.

Claude: more features, manual deployment
Ghosh reports using Opus 5 with low thinking in Claude desktop’s Cowork mode. Cowork could access the filesystem in this run, but could not check port availability or run the Docker Compose command. Ghosh selected port 8420, which he says was free, and ran Compose himself.
#1 Best Overall
The resulting app reportedly had active and completed-task filters, light and dark themes, and persistent tasks. Its implementation used Node’s built-in HTTP module, JSON-file storage, and a REST API. Ghosh says the project took about 3–4 minutes; he gives no comparable measured time for Gemini.
Gemini: more automated deployment, smaller feature set
For Gemini, Ghosh reports using Gemini 3.1 Pro with high thinking in Google’s Antigravity. Antigravity could use a terminal, check whether the port was available, and run the Docker deployment. The app was left accessible at a localhost URL.
The reported interface let users add tasks, mark them complete, and delete them, without the extra filters or themes in Claude’s app. It used Express and SQLite.

If “better” means fewer manual deployment steps in this particular setup, Gemini’s environment had the advantage: Antigravity handled the port check and Compose deployment, while Ghosh handled those steps himself in the Cowork run. That is a workflow advantage, not proof that Gemini’s underlying model is better at Docker.
If the desired result is a to-do app with more interface options, Claude’s reported output had more features. Whether that is an advantage depends on the brief: extra features can be useful, but they can also be scope the user did not request. Gemini’s simpler interface more closely matched a minimal feature set.
Both reports say the requested persistence was present, but the article does not provide an independent check of data surviving repeated container restarts or other reliability testing. Nor does it supply a shared scoring rubric, repeated trials, or evidence about long-term production readiness. The implementations also differ—JSON-file storage and Node’s built-in HTTP module in one, SQLite and Express in the other—so this was not a controlled comparison of identical code under identical conditions.

- Terminal permissions: Can the environment inspect the host, check port availability, and run Docker commands, or will you need to do those steps yourself?
- Acceptance criteria: Ask the tool to demonstrate that the container starts, the app loads locally, and data remains after a restart. Review the result rather than treating a successful build command as proof of every requirement.
- Scope: State whether you want only the requested features or welcome additions. Check that generated extras do not obscure the core task.
- Implementation: Inspect the Docker configuration, persistence method, and application code for your own maintenance and deployment needs.
- Production use: Treat a one-off generated app as a starting point. This comparison does not establish security, backup behavior, load handling, or production reliability.
What the result does—and does not—say
Ghosh’s conclusion was that both tools could build the requested Dockerized app, with the smoother deployment experience coming from the harness—in this case, the surrounding environment and its terminal capabilities. That is a useful observation about these two runs, not a general ranking of Claude and Gemini. The reported model labels, thinking settings, and tool capabilities reflect the configurations described in the August 30, 2026 article and may change over time.
