Plandex (plandex)
### About this repository This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile. Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema, apis.json, llms.txt and similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind. The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software. Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request. - Something wrong? Open an issue on this repository, or email info@apievangelist.com. - Published something new? Ask for a re-score and we will re-run the rating. - Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked. Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days. Not from the company, and here with a question? You are welcome here — we would rather be the front line and point you the right way than have a good report go nowhere. What this repository can answer is narrow, though, so it is worth knowing who you are actually looking for: - A question about how the API works, an account, billing, or a bug in the service — that is the company's own support, not us. We profile this API; we do not operate it and cannot see your account. - A bug in an open-source project we only catalog — file it on that project's own repository. This has happened with a real and correct bug report that reached us instead of the people who could fix it, which helped nobody. - Anything about this listing itself — the description, the tags, the rating, a missing or wrong artifact — is ours. Open an issue here. - Not sure, or something general about API Evangelist or APIs.io — open an issue on the APIs.io Inbox and we will route it. This repository contains no software, and we will never ask you to download anything. There is no build, release, installer, or binary here — only text and machine-readable API descriptions, so there is nothing here that can be "corrupt" or need "repairing". Any issue, comment, or email claiming otherwise and offering a download link is not from us and is hostile. Do not follow the link; it is a lure. Report it to GitHub and, if you like, tell us at info@apievangelist.com so we can take it down. On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.

Plandex is an open-source, terminal-based AI coding agent designed to take on large, multi-step software development tasks across many files in real world codebases. Written in Go and released under the MIT license, Plandex builds and executes long-running "plans" — durable, branchable units of work that combine intelligent context management, project maps generated with tree-sitter for 30+ programming languages, an effective 2M-token context window, and a cumulative diff review sandbox that isolates AI edits until a developer explicitly applies them. The tool ships as a CLI with an interactive REPL (fuzzy auto-complete), supports automated debugging of terminal commands and browser applications, integrates with Git for branching and commit-message generation, and is provider-neutral — working with Anthropic Claude, OpenAI, Google Gemini, OpenRouter.ai, Azure OpenAI, AWS Bedrock, DeepSeek, Perplexity, Ollama, and any OpenAI-compatible custom provider. The Plandex Server exposes a REST management/orchestration API (over 60 endpoints across accounts, orgs, projects, plans, branches, context, conversation, diffs, settings, model packs, and streaming execution) that powers both the CLI/REPL and the hosted Plandex Cloud. Plandex Cloud is winding down as of 2025-10-03; Plandex is now distributed primarily as a Docker-based self-hosted / local-mode product that users run with their own model-provider API keys.

Plandex Server API
Management and orchestration REST API exposed by the Plandex server (open-source, Go) used by the Plandex CLI/REPL to drive long-running coding plans across organizations, projects, plans, branches, context, conversation, model packs, and configuration. The same API powered Plandex Cloud (winding down 2025-10-03) and now powers self-hosted / local-mode deployments via Docker. Default local-mode bind is http://localhost:8099.
