Notion Completes Migration from Notion.so to App.notion.com.

Notion has completed its migration from notion.so to app.notion.com, marking the end of an era for the productivity platform's original domain.

The company announced on LinkedIn that the migration is now finished, describing it as "the same workspace, new home." The move represents a significant infrastructure change for one of the most widely used workspace tools, though Notion emphasized that users will experience continuity in their work.

The migration from a .so domain to a .com subdomain reflects Notion's evolution from startup to established platform. The .so domain, originally the country code for Somalia, has been popular with tech startups for its clever "so" wordplay possibilities. However, many companies eventually migrate to .com domains as they scale, seeking the familiarity and trust associated with the more traditional top-level domain.

For Notion users, the change means updating bookmarks and potentially re-authenticating in some cases, but the company has designed the migration to maintain workspace continuity. The .so domain likely redirects to the new app.notion.com structure, ensuring existing links continue to function.

The domain migration comes as Notion continues to expand its capabilities beyond traditional document editing. The company recently introduced a Developer Platform that gives developers new building blocks to extend Notion's functionality. The platform includes Workers for syncing external data sources into Notion databases and custom tools that agents can use to generate assets and query live data.

These technical expansions, combined with infrastructure changes like the domain migration, signal Notion's push to position itself as a comprehensive platform rather than just a note-taking app. The company has been aggressively developing AI features, including Custom Agents that handle entire workflows autonomously, and recently added an automated meeting agent to handle notes and Slack recaps.

The shift to app.notion.com also aligns with modern web application conventions, where the "app" subdomain typically indicates the working environment separate from marketing pages. This structure has become standard for SaaS platforms, making it immediately clear to users which URL leads to their actual workspace versus company information.

Notion has not provided detailed technical documentation about the migration process in the public announcement, keeping the message simple: same workspace, new address. Users accessing Notion through desktop apps or mobile applications likely won't notice any change, as these connect to Notion's servers regardless of the domain displayed in a browser.

For teams that have embedded Notion pages or built integrations using the API, the migration may require updating webhook URLs or OAuth redirect URIs, though Notion has not issued specific guidance on this. Organizations with strict firewall rules may need to whitelist the new domain to maintain access.

The completion of this migration, described with a simple salute emoji to the old .so domain, represents more than just a technical change. It reflects Notion's maturation as a platform and its commitment to infrastructure that can support its growing ambitions in AI, developer tools, and enterprise features.
