The local-first model
Local workspace data
Workspaces, environments, API collections, saved connection metadata, tabs, and related working context are available from the desktop application on the developer device.
Local credentials
API secrets, SSH credentials and key paths, database passwords, and credential references stay behind device-local boundaries and are resolved only when an operation needs them.
Remote systems being accessed
A local tool can still connect over the network to an API, SSH host, PostgreSQL or MySQL server, package source, or other remote target selected by the developer.
Optional cloud services
Sign-in, billing, updates, and optional synchronization may use online services. Their existence does not make the core workspace cloud-hosted, but each service has its own data boundary.
Why backend work benefits
- SSH passwords, private-key paths, and passphrases can remain tied to the developer device instead of being copied into a general-purpose hosted workspace.
- Database credentials and private network connection details can stay near the local tools that use them.
- API collections, environments, and variables can remain organized around the service or project they describe.
- Server, database, and API context can share one workspace, reducing repeated copying among unrelated SaaS tools.
- Debugging history and recent activity can remain useful local context without automatically becoming shared team data.
- Developers can keep core workflows available without making a paid cloud entitlement a prerequisite.
Trade-offs to plan for
Device migration
A new machine may need the application, local paths, credentials, private keys, and other device-specific configuration to be set up again.
Backup responsibility
Local-only workspace data depends on the developer or organization having an appropriate backup and recovery plan.
Team collaboration
Local context is not automatically a shared source of truth. Teams need explicit practices for which collections, tasks, or configuration should be shared.
Multi-device synchronization
Without optional sync or a manual transfer process, supported workspace changes made on one device do not automatically appear on another.
Remote access
A desktop-first workspace is less convenient when the developer needs browser-only access from an unmanaged or temporary device.
Device security
Keeping sensitive context local makes operating-system accounts, disk encryption, screen locking, malware protection, and device disposal practices important.
How Unfour applies local-first
Unfour is one desktop application with a free, open-source core. Its API Client, SSH and SFTP, database tools, MCP-assisted workflows, and local workspace functionality do not require Pro.
- The core desktop workspace is local-first and available without signing in.
- Credentials, secret values, credential references, SSH private keys and paths, local database files, and runtime history remain local.
- Pro is an optional entitlement in the same application and currently unlocks Cloud Sync for supported workspace data.
- Cloud Sync is optional. Supported non-secret workspace data may be synchronized across devices when the user enables it and has an active Pro entitlement.
- Device-specific paths and unsupported secret data must still be configured locally on each device.
MCP in a local-first workspace
Unfour runs its released MCP server as a local stdio process. A compatible client starts that local process, which opens the same local Unfour workspace data and uses Unfour policy boundaries to perform approved operations.
- Guided setup is available for Codex and Cursor; other MCP-compatible clients may connect when they support a manually configured local stdio server.
- The MCP process can resolve local credentials when an approved saved operation requires them, but tools do not return raw credential values.
- Approved tool results can be returned to the connected AI client, so review that client and its data-handling boundary instead of claiming the AI can never see operational data.
- Workspace scope, environment policy, redaction, and content-bound confirmation constrain the Unfour side of the connection; they are not a guarantee that every agent decision is correct.
When the model fits—and when it may not
A strong fit
You work from a managed developer device, access private APIs, hosts, or databases, want core workflows without mandatory cloud storage, and can manage local backup and credentials.
A weaker fit
Your primary need is instant browser access from any device, real-time shared editing for a large team, or centrally managed operational context with no local setup.
