The best local-first Mac apps: no account, no cloud

A local-first Mac app stores your data on your device by default and does not require an account to use. Sync, if it exists at all, is optional and usually opt-in. This is different from most modern software, which treats your Mac as a thin client for a server it controls. The apps below were checked against their own documentation and current pricing pages to confirm they still meet that bar in 2026.

What does local-first actually mean?

Local-first is a specific claim, not a vibe. It means three things have to be true. First, the app's primary copy of your data lives on your Mac's file system or a local database, not a remote server. Second, you can open, edit, and use the app fully offline, with no connection required. Third, no account or sign-in is required to use the core product. Cloud sync can still exist as an optional layer on top, often through your own iCloud account or a separate opt-in service, but it should never be the only way the app works.

This rules out a lot of software that markets itself as "offline-capable" while still routing your data through a server the moment you open the app. It also rules out apps that store data locally but refuse to function at all until you create an account and log in.

The best local-first Mac apps in 2026

These six apps span notes, document management, task tracking, writing, and media history. Each stores its primary data locally and lets you use the app without creating an account.

Obsidian: notes and knowledge base

Obsidian stores every note as a plain Markdown file in a folder on your Mac called a vault. There is no account requirement anywhere in the core app, no telemetry, and no server that holds a copy of your notes unless you deliberately add the paid Sync add-on. Because notes are plain text files, you can open, search, and edit them with any other text editor if you ever want to leave. Obsidian's own documentation describes this as a deliberate local-first design, and the core app is free for personal and commercial use, with Sync and Publish sold as optional paid add-ons rather than requirements. See Obsidian's data storage documentation for the full breakdown.

Bear: notes with optional iCloud sync

Bear keeps your notes in a local database on your Mac. If you turn on sync, it uses CloudKit and your existing iCloud credentials, so there is no separate Bear account to create or log into. The company does not run its own servers that store your notes. The free tier gives you full local access to writing and organising notes; a Bear Pro subscription is only required to unlock sync across devices and extra themes, not to use the app locally.

DEVONthink: document and information management

DEVONthink keeps its databases as local files on your Mac, typically stored in a folder like ~/Databases, and it never uploads your documents to DEVONtechnologies' own servers. Logging into a DEVONtechnologies account is only needed for license activation, not for storing or accessing your data. If you sync between devices, DEVONthink encrypts the data before it touches whatever storage location you choose, whether that is Dropbox, a NAS, or nothing at all.

Things 3: task management

Things 3 stores your tasks in a local database and works fully offline with no setup required. A free Things Cloud account is only needed if you want to sync tasks across more than one device or your Apple Watch; a single-device setup needs no account of any kind. Things Cloud is Cultured Code's own sync service, separate from your personal iCloud account, and it remains optional rather than a requirement to open and use the app.

iA Writer: writing

iA Writer added an explicit local storage option, labelled "On My Mac," that keeps your files entirely on-device with no account of any kind. iCloud is the recommended default for syncing across your own Apple devices, but the app is storage-provider agnostic: you can point it at a local folder, iCloud Drive, or another provider, and it never requires you to sign up for an iA account to write, save, or export.

Echo: media memory

Echo is a native macOS menu-bar app that remembers what you have played across native apps like Spotify and Podcasts, and across the browser, including YouTube and SoundCloud. It builds a searchable history of everything and lets you resume any track or video at the exact spot with a keystroke. Unlike the note-taking and task apps above, media history is the one category where almost every competitor requires an account or reports your listening to a company server for recommendations. Echo does neither: there is no account of any kind, no cloud component, and nothing leaves your Mac. It is a one-time $9.99 purchase covering up to three Macs and every future update.

How do these apps compare?

Why choose local-first software over cloud apps?

Three practical reasons keep coming up. Speed: a local database or file responds instantly, with no network round trip. Longevity: a plain-text vault or local database still opens in ten years even if the company that made the app is gone, while a cloud account can vanish with the service. Privacy: if your data never leaves your Mac, there is nothing for a server breach, a policy change, or a company acquisition to expose.

The tradeoff is that local-first apps generally ask you to manage your own backups and, if you want sync, to set it up deliberately rather than getting it by default. For most people that is a reasonable exchange: you get speed, durability, and privacy, and you opt into sync only when you actually need it.
