Start with the open-source library. Graduate to the cloud when you need persistence, concurrency, or a fleet.
One agent, one machine
CLAUDE.md or AGENTS.md
Fine as a scratchpad.
One agent, persistent state
Nodiom open-source
Structural editing, no file corruption.
Many agents, shared state
Nodiom Cloud
Locking, history, no race conditions.
Try it. No card, no surprises.
Single-agent production use.
When your agents become a fleet.
Isolated environment, SLA, procurement.
Any successful call to one of Nodiom Cloud's MCP tools — reading a section, appending to it, writing, or deleting. Failed calls (errors, invalid selectors) are never counted.
Requests are blocked until the next monthly reset. No charges, no surprises — the Hobby cap is a hard limit, not a billing trigger. Upgrade to Pro when you need more capacity.
On Scale, concurrent writes to the same document from multiple agents are guaranteed correct — writes queue behind each other at the database level so none are lost. On Hobby and Pro, if two agents attempt to write simultaneously, you get a clear error rather than a silent race condition. Single-agent use on any tier is unaffected.
Yes — the core nodiom library and nodiom-mcp server are open-source (MIT). Nodiom Cloud is for teams and individuals who'd rather not run and scale it themselves.
