Shawn Welch built Zeltro because his vibe coding side projects kept falling apart between sessions: folders everywhere, terminals left open, and apps he could not get running again a few weeks later. In a September 29, 2026 post on DEV Community, he describes a desktop “home base” meant to keep each project in one place, with a suggested setup and an AI agent working inside the same window. This article explains what he says the app does, which parts are his own claims, and what to check before trying it.
The problem: projects that stop working between sessions
Welch runs a computer repair shop and builds apps on the side. His core complaint is not that AI coding tools fail to produce code. It is that returning to a project takes time he does not have. In his words: “Most of my vibe coding turned into a mess of folders, terminals and half finished apps I couldn’t get running again a month later.”
The same frustration shows up in community discussions. One Reddit thread asks, “How are people keeping larger vibe coded projects from slowly turning into a mess?” That question shows the concern is common enough to be asked, but it does not measure how many builders share it.

What Zeltro is meant to do
According to Welch’s post, Zeltro is a desktop workspace with four main parts. Each one addresses a specific cause of lost time when you come back to a project.
#1 Best Overall
- 12th Intel Alder Lake N95 Processor – The GMKtec G3 S Mini PC is powered by the 12th Gen Intel N95 processor with 4 cores, 4 threads, 6MB cache and a burst frequency up to 3.4GHz. Compared with N100/N5105/N5100/N5095, the N95 delivers up to 36% overall performance improvement. Perfect for routine tasks, office work, and home entertainment, this compact mini desktop is more convenient than traditional bulky PCs.

All defects due to design and workmanship are covered. With a professional after sales team always ready to attend to your needs, you can simply relax and enjoy your mini PC
- Guided setup: you describe what you want to build, and the app suggests a setup along with the reasoning behind it.
- Embedded terminal: you work with an AI agent inside the app rather than switching between separate terminal windows.
- Per-project addresses: each project gets its own address, which he says avoids port conflicts when several apps run at once.
- Shared database: projects share one database, so you do not repeat database setup for every new app.
Why separate addresses matter
Two local apps that both try to use the same port will clash, and one of them will fail to start. Giving each project its own address removes that collision. The benefit is mainly for people who keep several unfinished apps on one machine and switch between them.
Why a shared database is a trade-off
A shared database saves setup time, but it also means projects can see each other’s data. Welch’s post presents sharing as a convenience. It does not describe how the separation between projects is handled, so treat that as a question to answer before storing anything sensitive.
Credentials and notifications: the author’s claims
Welch says the app asks for API keys in a private input box instead of asking you to paste them into the chat with the agent. He also says Zeltro notifies you when an agent finishes a task or needs your input, which helps when you leave a long task running.

Easily configure it into software routers, hardware firewalls (pfSense, OpnSense), home NAS servers, or local homelabs.
These are product claims from the developer. The post does not explain how keys are stored, whether they are encrypted, or what the app’s threat model covers, and it does not cite an independent security review. Keeping keys out of chat is a sensible design goal, but it is not the same as a verified security property.
Which AI tools it supports and how you pay
Welch names five options: Claude Code, Codex, Gemini, Qwen, and local models. The app does not sell AI access. Instead, you use an API key or subscription plan you already have with a provider, or a free local model, and you pay the provider directly.
This means your AI costs stay with your existing provider account. Zeltro’s own price is not the only cost to consider. Usage with a cloud agent is billed by that provider under its terms, while a local model avoids that bill but depends on your own hardware.

Everything above comes from Welch’s own description. The post does not compare Zeltro with competing tools, and it does not report hands-on testing by an outside reviewer. Its claims about project isolation, shared databases, credential entry, and notifications are therefore the developer’s account of how the app is meant to work.

How to evaluate a tool like this for your own projects
If you are considering a project home base, test it against the problems it claims to solve before you move real work into it. Use this checklist:
Recommended Free Tools
- Port handling: run two test apps that default to the same port and confirm each gets its own address.
- Database boundaries: create a table in one project and check whether a second project can read or change it.
- Key entry: find where API keys are stored after you enter them, and confirm they do not appear in the chat transcript.
- Notifications: start a long agent task, switch windows, and confirm you are alerted when it finishes or pauses for input.
- Portability: check whether your project files remain ordinary folders you can open, back up, and run outside the app.
- Cost: estimate monthly spend on your chosen provider, or confirm that a local model runs acceptably on your machine.
Welch’s central idea is sound regardless of any single product: a project that is easy to restart is a project you are more likely to finish. Whether Zeltro delivers that for you depends on the checks above, not on the post alone.
