Frigade, the Y Combinator W23 startup, released Hob on Oct. 26, a free, MIT-licensed desktop assistant that runs open-weight models locally on macOS, Windows and Linux. It is pitched as an on-device alternative to Claude Cowork and the ChatGPT desktop app.
The company announced the project in a "Show HN" post on Hacker News, where the thread had 162 points and 39 comments as of Oct. 27. The post's author, Christian, whose Hacker News profile lists him as CTO of Frigade and whom the company's About page names as a cofounder, described it as "a free, MIT-licensed desktop app … except the model runs on your own computer." According to him, Hob works on local files the way the Claude and ChatGPT desktop apps do.
What Hob can do
Hob currently runs Gemma 4 and gpt-oss. Image recognition is handled by a small Qwen3-VL model, and dictation by a local Whisper model. Because it supports the Model Context Protocol (MCP), an open standard for linking AI tools to outside data and services, users can add connectors, including remote servers.
The app can also write sandboxed Python for ad-hoc jobs like data processing, document conversion and charting. Christian wrote that the sandbox relies on sandbox-exec on macOS, Landlock on Linux and a low-integrity process on Windows, with "no network unless asked."
How Hob picks a model, and what it says about privacy
On first install, Hob chooses an open-weight model suited to the user's hardware. "It will automatically pick the best [model] for your HW on install," Christian wrote in a reply on Oct. 27.
His examples ran the range. An 8 GB Mac (M1/M2) gets Gemma 4 E2B, a 128 GB Mac Studio gets gpt-oss 120B, and a machine with an RTX 4090 graphics card runs Gemma 4 26B entirely on the GPU. Replies in the thread indicate the selection aims for a minimum of roughly 15 tokens per second, and that Windows and Linux support setups that split work between GPU and system memory.
On privacy, Christian wrote: "All your chats and files never leave your system." The only online features are an optional built-in web search, powered by SearXNG, and any MCP connectors a user chooses to add. Search can be turned off. Still, Frigade has not published a formal privacy document specific to Hob, and no explicit telemetry or account policy turned up in the research for this article, so the privacy claim rests for now on the developer's word and the open-source code.
Electron, llama.cpp and the case against existing tools
Christian wrote that he built Hob "using Electron bridged with llama.cpp in its own process." Electron, a framework for building desktop apps with web technology, is sometimes criticized for heft, but he defended the choice: "even Claude's own Desktop app is made in Electron."
He also said existing local apps struggled with larger files, images or reliable tool use. With small models in particular, he wrote, dependable tool use required "guards" rather than prompt tweaks.
A crowded field
Hob competes with the cloud-based Claude Cowork and the ChatGPT desktop app, and with local tools mentioned in the thread: Jan, OpenWork, Chatbox, Lobe Chat and Open WebUI. LM Studio, Unsloth Desktop and the llama.cpp native app also came up. Christian said the local options did not meet his needs for file workflows and tool use.
Early traction is modest but visible. The GitHub repository showed 236 stars and 12 forks on Oct. 27, and Frigade has not disclosed download counts or active users. The Releases page lists v0.2.0 and v0.2.1, both dated Oct. 26. Notes for v0.2.0 refer to an earlier name, "Garth," and the creator confirmed the rename in Hacker News comments.
Readers should not confuse it with hob.dev, an unrelated subscription "agentic workspace" from SmartAppsCo.
Frigade's background
Frigade, based in San Francisco, was founded by Eric Brownrout and Christian Mathiesen. Its About page cites prior roles at LinkedIn, Discord and Digit, and LinkedIn lists the company at 2-10 employees.
The company announced a $3 million seed round on July 24, 2023, led by Craft Ventures and La Famiglia, according to PR Newswire. Y Combinator, Defy.vc, Magic Fund and angel investors including Guillermo Rauch, Arash Ferdowsi and Jean-Denis Greze took part. The About page also lists General Catalyst, which the 2023 release did not name. No newer round has been announced publicly.
That seed money backed a developer tool for product onboarding and adoption. Hob is a different kind of product from the same small team, and the launch materials do not detail how Hob will be funded or monetized.
For now, Christian's stated goal is a narrow one: an assistant that does what the cloud desktop apps do, on hardware people already own.
