Solid

Solid is an AI agent platform whose agents get their own machines, accounts, and budgets to carry out long-running work such as building apps and automating workflows, billed from a single prepaid balance.

Solid is an agent platform built for complex, long-running work rather than quick chat replies. Each agent can provision real machines, including Linux servers, Windows and macOS computers, and iPhone or Android devices, create accounts for the services a job needs, and make purchases within the budgets and approval rules the user defines. Agents work through APIs where they exist and log into web apps like a person where they do not, building missing pieces and fixing problems along the way. A distinctive design choice is the single balance. Each subscription (Starter, Pro, or Max) adds its full price to an account balance, and AI usage, machine time, and agent purchases all draw from it, with Solid stating it charges nothing on top. Because agents are described as meta-agents that can see their own workspace, users can ask what is running, why, and what a job cost, and get a breakdown by AI, machines, and purchases. Solid launched on Product Hunt in the week of September 21, 2026, positioning itself beyond personal agents toward team work that runs after the laptop is closed. It offers an API and a team or enterprise track via sales. Buyers should treat spending controls and approval rules as the first thing to configure.
