Local GGUF models served by llama.cpp, a desktop app, and zero network calls. Completion, chat, and code explanation work with the internet unplugged — on a laptop, a lab PC, or a machine that will never be allowed near a cloud API.
Product Hunt & Open Source Awards
CodAI was awarded Product of the Day, Product of the Week (Developer Tools), and Product of the Month (Open Source). Free, local, and audited.
One portable Windows zip. No installer, no account — unzip on any writable drive, including a USB stick for lab machines.
Any GGUF works — drop it into models\. The default pick, gemma-3-1b-it (0.81 GB), runs on 2 GB-RAM machines via the bundled llama-server engine.
Completion, chat, and explanation run against 127.0.0.1. Pull the network cable mid-session — nothing changes, because nothing was talking to the internet in the first place.
Any quantized GGUF works with the bundled llama-server engine. Start with the default and size up as your RAM allows — every model here runs on CPU, no GPU.

| Source code transmitted | None | Every request |
| Account / API key | Not required | Required |

| License | GPL-3.0, inspect it all | Proprietary terms |
University machines block installs and cloud sign-ins. CodAI runs portable from USB and needs no network at all.
Proprietary logic never leaves the building. No prompt logs on someone else’s server, because there is no other server.
Planes, ships, remote sites, metered connections. The assistant is fully functional at zero bandwidth.
The default model runs on 2 GB-RAM machines; 4 GB covers the 1–2 GB class. No GPU, no subscription, no minimum spec beyond a 64-bit OS.
Local AI, WebGPU, authentication, and privacy engineering — written on this machine.
GetForms launches as a free, open-source form backend with unlimited forms, silent spam filtering, 25 MB uploads, and multi-channel alerts. Tested against Formspree, Formcarry, Basin, and FormBee with current pricing.
Is Qoder safe? Qoder says it does not store code-completion context, but its privacy policy lets certain User Content be processed and retained for up to 5 years.
Compare API Keys and JWTs, understand their security differences, use cases, advantages, and learn when each authentication method is the right choice.
Learn the difference between Base64 encoding and encryption, why Base64 offers zero security, common developer mistakes, and when to use each correctly.
Free, open source, and yours to inspect.
