Tools for the Personal Software Revolution

AI labs are shipping frontier models that are inverting the physics of software development, capable of creating SaaS-grade software in a fraction of the time and cost. Months condense to weeks, and weeks into hours. Meanwhile, open-weight models continue to become cheaper, more capable, and more accessible.

The barriers of entry for those without experience building software are lower than ever, opening the potential for a new open-source participation economy.

This is radical platform engineering for the masses.

Just as server rooms gave way to personal computers, and obscure terminals gave way to GUIs, AI in the cloud will soon give way to frontier-class, open-weight models running on consumer hardware.

The software engineers of yore, those architects with the experience and expertise around best practices and system design can lead the charge, opening the doors to software that’s 100% agentic, but still secure and well-built, aimed at the Citizen Developer.

This is a challenge to the enshittification pushed by Big Tech and Big AI. We can replace their vision with a different way of building. An agentic codebase, written with AI as the primary developer and optimized for the model rather than for the human developer. Not so we can line the pockets of the AI labs, but so we can empower the humans who benefit from free, open, transparent, and malleable software.

This is the personal software revolution. It doesn’t get more personal than one person sitting at a computer, telling it what to do: local-first, open-weight, and open-source, not as a fashionable posture, but as a means of liberating software from the gatekeeping of developer nerds and greedy corporations.

solo.ist is an experiment in exploring these ideas. How we build needs to align with why we build. The means must match the end: personal software that’s truly personal, generated for your needs, not someone else’s bottom line.

Projects
Prose solo.ist/prose Live
A free, open-source markdown editor for the AI era. AI knowledge workers know markdown is at the center of everything. Prose reimagines the humble markdown editor with a clean, minimal, and elegant base, while providing optional AI that doesn’t strive to write for you. Writing modes put you in control, suggestion and comment review let you keep up with feedback from humans or AI, and activity history and in-document provenance annotations keep track of where changes came from. It’s local-first, so your files are plain .md (or .txt). The open-source build goes further: an MCP server lets Claude Desktop read and edit your documents and interact with the app. New web-based features are coming, starting with the ability to share a document as a link so people read and provide feedback, with the comments coming back into Prose.

Prose is one expression of the solo.ist idea of personal software. Why pay for Obsidian or iA Writer, when you can roll your own, or fork a solid starting point.

Termy solo-ist/termy Soon
Managing agent fleets and software factories is a headache. Termy is a terminal app that gives you a durable session plane where the agents actually run, sitting on top of a custom meta-harness that lets you orchestrate across Claude, Codex, and most importantly, steer towards increasingly capable open-weight models. Manage the cognitive overhead of AI software development, without becoming a reverse centaur, a meat proxy for your LLMs. Termy is for humans who want to put AI to work for them, not the other way around.

Solo Prime Coding Harness solo-ist/harness Soon
A local-first, open-weight centered, durable orchestration layer for managing fleets and swarms of coding agents. A local, Temporal-backed plane takes your intent as a goal and runs it as a loop — plan, build, review, land — surviving restarts, crashes, and the agent changing its mind. For now, a frontier model orchestrates, but open-weight models on local hardware become the workhorses. This is the software factory that powers the personal software revolution, the engine the rest of these tools get built with.

Built by me, Angel Marino.

solo.ist is the home for tools I build because I want them and the version I need or want doesn't exist. Everything is local-first, open-source, MIT licensed, and designed to work for humans and agents alike.
