What is local-first software?
Local-first software keeps your data and computation on devices you control, treating the cloud as an optional accessory rather than the landlord. You own the files; sync and scale are choices.
Ownership is architectural
Whether you control your data is decided by where the software runs, not by a privacy policy. Local-first puts the primary copy — and for AI, the keys and memory — on your machine by construction.
Why it matters doubly for AI
Agent systems accumulate exactly what you least want hosted by strangers: credentials to everything, a memory of your operations, and a log of every decision. Local-first keeps that corpus yours.
Cost follows architecture
Cloud automation meters every operation. Software running on your own hardware makes marginal runs free — which changes what you are willing to automate.
How to evaluate a claim of local-first
Vendors use the phrase loosely, so test it with three questions. If the company disappeared tomorrow, does your installed copy keep working? Where are the credentials stored, and can you read them off your own disk? Does using it require an account at all? Software that fails any of these is cloud software with an offline mode, which is a legitimate product and a different one.
Common questions
Is local-first the same as offline?
No — local-first software uses the network freely; it just does not require it for your data to exist and your tools to run.
Can local-first scale to a team?
Yes: AGNT pairs local runtimes with optional cloud and self-hosted deployment for shared operations.
What is the trade-off with local-first?
You take on the machine: storage, updates and backups are yours. In exchange the data, the credentials and the marginal cost of a run are also yours.
