Aefos AI 1.2.0

Aefos AI is free software

The source is published, the licence gate is gone, and every feature ships enabled — the Terminal, the MCP server and the agent tools. There is no key, no activation, no trial and no editions.

The gate was not disabled, it was removed: the package, its four units, the activation dialog, the menu items, the trial badge, the "(Pro)" tags and all 44 call sites across both the RAD Studio and Lazarus editions. Aefos no longer contacts any backend of ours, so nothing about your machine is registered anywhere.

Licensed under the GNU GPL v3, with two additional permissions (ADDITIONAL-PERMISSIONS.md): the code Aefos writes for you is yours, under any licence including a proprietary one — and linking with the RAD Studio libraries is expressly permitted, without which a design-time package could not be distributed at all.

Downloads

	Installer	IDE
RAD Studio	Aefos-Setup-1.2.0.exe	Delphi 13 (BDS 37.0) and Delphi 12 Athens (BDS 23.0) — the installer detects what you have and lets you pick
Lazarus (beta)	Aefos-Lazarus-Setup-0.25.0-beta.exe	Lazarus with FPC 3.2.2, 32-bit or 64-bit

🆕 64-bit Lazarus is accepted for the first time

The Lazarus installer now carries an x86_64 payload beside the i386 one — libvterm.dll, sqlite3.dll and WebView2Loader.dll — so the wizard stops refusing a 64-bit IDE. Close Lazarus before installing: it rebuilds lazarus.exe, backing yours up first. Full notes: RELEASE-NOTES-0.25.0-beta.md.

⚠️ The installer no longer bundles an AI CLI

1.1.0 shipped Codex and Gemini inside it. Open source changes that trade — redistributing third-party binaries adds licence surface and ships versions that go stale — so the installer drops from 109 MB to 5.5 MB. Aefos is bring your own CLI: install the one you already use (Claude Code, Codex, GitHub Copilot CLI, Gemini) and point Aefos at it, or leave the executor path empty and let it be found on PATH.

Upgrading from 1.1.0 loses nothing — the bundled binaries were installed with uninsneveruninstall, so your copy in %APPDATA%\Aefos\bin stays.

Delphi 11

Not supported. Earlier documentation said otherwise; no 22.0 build has ever existed, so the claim was removed rather than left to disappoint someone at install time.

Build it yourself

Everything shipped here builds from this repository, with no absolute paths:

scripts\build-packages.ps1 -Version all
installer\build-installer.ps1

Both installers in this release were built exactly that way, from a checkout with no libvterm objects — the build generated them. See Build from source and CONTRIBUTING.md; an issue or pull request description may be in Portuguese.

Supporting the project

Aefos is free software and stays that way — there is no paid tier. What keeps it moving is the AI subscriptions its own development runs on, paid by one person. Pix (random key): 4b155305-2671-4c39-8d58-7b9b5c428e18 · other ways to contribute
