Plandex
Open-source terminal coding agent; development stopped, cloud closed November 2025
Overview
Plandex is an MIT-licensed, self-hosted CLI agent for large multi-file coding tasks, with a version-controlled diff sandbox and a claimed 2M-token effective context. Plandex Cloud closed on 7 November 2025, plandex.ai no longer resolves, and the repository has had no commits since 3 October 2025.

Use cases
What you can produce with Plandex
- A self-hosted, MIT-licensed CLI agent with prebuilt binaries on GitHub releases
- A cumulative diff review sandbox before changes are applied
- Plan branching and rollback of agent-generated changes
- Large effective context with tree-sitter project maps
- Multi-provider model support across OpenAI, Anthropic, Google and OpenRouter
- Automated debugging against build, test and lint commands
Plandex's core idea still holds up: a terminal agent that plans a multi-step task, keeps every change in a reviewable sandbox until you approve it, and lets you rewind or branch a plan. For a refactor across dozens of files that is a safer workflow than agents writing straight to disk.
But the project has stopped: the company wound down in October 2025, the cloud closed in November, and plandex.ai no longer resolves, breaking the installer. It still runs from GitHub release binaries with your own keys. Do not build a team workflow around it.
What we found
Plandex is an open-source, MIT-licensed coding agent that runs in the terminal and is built for large tasks touching many files. Its creator, Dane Schneider, started it in late 2023, launched it on Hacker News in April 2024 and shipped a substantially rebuilt version 2 in April 2025. Its distinguishing ideas hold up: changes collect in a version-controlled sandbox until you approve them, plans can be rewound or branched like git history, and it mixes models from Anthropic, OpenAI, Google and OpenRouter. The README claims two million tokens of effective context and tree-sitter project maps that index far more.
The company behind it has stopped. On 3 October 2025 Schneider announced he had joined Promptfoo and was winding down Plandex as a business: new sign-ups closed, subscriptions stopped renewing, and Plandex Cloud shut down on 7 November 2025. The post names competition from foundation-lab agents, Claude Code and OpenAI's Codex among them. The last commit to the repository is from that same day, and the newest release, 2.2.1, dates from July 2025.
The practical consequence goes beyond unmaintained. plandex.ai no longer resolves, which breaks the documentation site and the documented one-line installer, because that script fetches the current version from the dead domain. The software still works from GitHub: prebuilt binaries for macOS, Linux and FreeBSD are attached to the releases, and the server runs locally in Docker with your own API keys. Windows needs WSL. Earlier versions of this page quoted a directory's "best open-source agent" line that the same directory contradicts.
Early users on Hacker News praised the sandbox and branching but reported friction setting up version 2, including sign-in and model-pack configuration. There is no official IDE extension. Plandex suits a developer happy to self-host frozen code; anyone choosing a tool to build a workflow around should treat it as archived in all but name.
