Fulling: review, pricing, security and alternatives
Fulling is an open-source AI agent published by FullAgent, in the coding agents family. Fulling is a Claude-based full-stack development agent with a Next.js application and Kubernetes infrastructure. Its repository has 2,444 stars and its last commit is from July 21, 2026.
What Fulling does
Fulling belongs to the coding agents family: they read a repository, edit files, run the tests and fix things until everything passes, in a terminal or an editor. On our grid it ranks #51 of the 74 projects of this family listed in the directory.
You use it from: web app. Usable models: Claude (Anthropic). It can run on your own machine or server.
Who is Fulling for?
It is aimed at developers and technical teams who want to hand off part of the work on their codebase while keeping the final review. Typical tasks people give it:
- fix a bug from an issue or an error message
- write or extend tests
- migrate code to a new library version
- explain an unfamiliar codebase
It is a good candidate if you prefer doing everything in a browser, with no install and your data must stay on your machines.
Access and human control
Its documentation does not detail the access granted to the agent: check the settings before connecting it to your accounts.
We could not establish whether it asks for human approval before sensitive actions: test it first on an unimportant account or folder.
Fulling pricing
The code is free, under the MIT licence.
Getting started with Fulling
- Install it: the project ships as a Node.js package (install with
npm, or run directly withnpx). The exact command is in the repository README. - Create an API key with the model provider and put it in an environment variable, never in a shared or versioned file.
- Give it a first playground with nothing at stake: a test folder, a secondary account or a throwaway project. Only open your real accounts once you have seen how it behaves.
- Give it a short, checkable task, review the result and its action log, then raise the difficulty step by step.
Security: risk level
A coding agent runs commands on your machine: work on a Git branch, review the changes and isolate it in a container for long tasks.
Three habits: least privilege (minimal rights, dedicated keys), human approval for irreversible actions, a sandbox for code execution. The AI agent security check reviews your setup in a few minutes.

Fulling vs other coding agents
GitHub stars of the best-rated open-source projects in the coding agents family. Stars measure attention, not quality: a heavily promoted project collects them fast, a specialised tool will have few.

The software is free (MIT licence). You still pay for the model calls, unless you use a local model.
Is Fulling safe?
Our risk level: low. Give it minimum rights and approve irreversible actions.
Which models does Fulling use?
According to its documentation: Claude (Anthropic).
Can Fulling be installed on your own server?
Yes, from the FullAgent/fulling repository. Data then stays with you, but security and updates are your job.
What are the alternatives to Fulling?
In the same family: OpenCode, Cline, OpenHands, and Codex.
Fulling or OpenCode: what is the difference?
Both belong to the coding agents family. Fulling has 2.4K stars against 221K for OpenCode. The right choice mostly depends on the access you are willing to give it.
