“For SpacePlanner, another agent does. Three agents build: one for design, one for SEO, one for code. A fourth one has a single job, to break whatever they made before it goes live.”
Editor's note: Jimmy Mass builds SpacePlanner alone, next to a full-time job. He runs Claude Code on a server that he reaches from his phone: builder agents for design, SEO and code write each change, a fourth agent tries to break it, and 4,649 tests decide whether it ships. He says the app is "744 commits since June, almost all written by coding agents on one server" (Oct 1, 2026). The stack is Supabase, Vercel Pro and Cloudflare R2. TrustMRR gives a founded date of Dec 5, 2024 and Romania; his X profile says London, and his own posts date the current push to June 2026. His X bio links SpacePlanner.co, and TrustMRR links the listing to the same account.
How they got customers
No signup wall: anyone can draw a plan as a guest, and an account is only needed to save across devices or export. A creator put SpacePlanner in a "powerful websites" series on Instagram without being asked (424K views), and his onboarding survey says most users found it on Instagram, TikTok, Facebook and YouTube; almost none came from X. About 30% of sessions come from Google, mostly people searching the name after seeing it on social. He translated the app into Spanish, Indonesian, German, Polish and Italian with an LLM, and the app records its own tutorial videos every night for social posts.
Steps to try
Remove the signup wall: let people use the editor as guests and ask for an account only when they need to save or export.
From the sourceAsk new users where they found you; his survey showed Instagram and TikTok, not X, where founders hang out.
From the sourceGive coding agents separate jobs and add one whose only job is to break the change before it ships.
From the sourceTranslate early with an LLM and fail the build on missing strings so every language stays complete.
From the sourceMonetize a free tool with small credit packs; $9 packs turned a usage spike into $711 in a month.
