Solid

Solid began as an AI builder of production ready web apps and has relaunched around autonomous agents that have their own computers, accounts and budgets. A user describes a job in plain language, such as a tested sales demo, a researched lead list or a weekly report, and Solid's agents work out the steps, connect to whatever tools the job needs, build any missing pieces, check the result and message back with finished work while the user's laptop is closed. The agents operate their own Windows and macOS computers, Linux servers, iPhones and Android phones, hold their own Google and Apple accounts, and can sign up for and pay for services within the budgets and approval rules the customer sets. They can use any tool a person can use without a prebuilt connector, by calling an API, building an integration or operating a website, desktop program or phone app directly. They repair their own broken setups, keep lessons from team corrections, and can create more Solid agents or bring in Codex and Claude Code to split up larger jobs. An API lets companies embed always on agents in their own products, and enterprise customers can set access, budgets, policies and approvals and run on Solid Cloud, in their own VPC or on premises. The original app builder at trysolid.com still promotes enterprise internal tools with EU or US hosting, audit logs and encryption. There are three monthly subscriptions: Starter at $40, Pro at $160 and Max at $640. The full amount goes into the account balance, from which AI usage, machine time and approved agent purchases are deducted, with no platform fee on top. New users get a $20 free trial, and larger workloads can be priced on a call.
