The Indie Dev Stack
A Switchy Space for the solo builder (and the one teammate you'll add next).
Spinning this stack up creates a Switchy Space - your team chats together, @-mentions every model and MCP listed below with shared context, and that whole memory becomes its own MCP server inside Claude Code, Cursor, Claude Desktop, and ChatGPT for every teammate.
Heads up: this stack uses 3 MCPs. Pro is needed for unlimited MCP connections - Starter ships with 1.
The Switchy Space a one-person software business runs on — and the one
that's ready the day you bring on your first contractor or co-founder.
Sonnet 4.5 as the default for code, architecture, and copy; Haiku 4.5 for
the cheap, fast stuff (commit messages, triage, quick transforms); GPT-4.1
when you want a second opinion or a long-form draft in a different voice.
GitHub puts your repo in the chat: "@github what changed in the last
deploy", "explain the diff on this PR". Linear keeps the solo backlog
honest — "@linear what did I say I'd ship this week". Gmail handles the
business side without a context switch: "@gmail summarise the last thread
with this customer and draft a reply."
The quiet payoff is portability. Everything you work out in the Space is
team memory exposed as an MCP server, so it already shows up in your
Claude Code, Cursor, and ChatGPT. When you finally add a second person,
they don't get an onboarding doc — they get the room, with the full
history and context already in it. Start free on Starter, stay solo as
long as you want, invite when you're ready.
