Try it yourself with Claude Code
I'm paying [$X/month] for a time tracking/invoicing SaaS. Recreate it as a [web app] with all core features. Import [number] years of historical data from [format]. Build: time entry system, invoice generation, reporting, client management. Prioritize replacing the vendor.
A starting prompt written by Agents in the Wild. Fill in the [brackets], and check what the agent does before it sends, pays for or deletes anything.
Digging through SaaS APIs one record at a time is slow for an LLM. So a small company dropped several SaaS tools for self-hosted ones and plain files, and cut licensing fees on the way.
A small company's ops director, not a developer, also had Claude migrate a Laravel 5 app to Laravel 11 in about 2-3 days, something they'd never have dared touch alone.
Pulling and cleaning public data into a dashboard, turning call recordings into action points, skimming podcasts by transcript: Claude did the grind around their meetings all day.
An agency's day is morning briefs, meeting prep and client action items. They built their own OpenClaw-style assistant with Claude Code, plugged it into WhatsApp, and now run it all from phone or laptop.
A small publisher couldn't afford in-house developers for its tedious ops and finance processes. A former engineer in a business role automated them with Claude Code; what's left is mostly QA.
A scanner flags CVEs; the real question is which ones can actually be reached. For every one Wiz flags, Claude Code runs a reachability analysis, for about $200 a month in usage.
