If Windsurf autocomplete has suddenly stopped working, there’s a good chance it’s not a bug at all – Windsurf was rebranded to Devin Desktop after Cognition (the company behind the AI agent Devin) acquired it. Existing settings, extensions, and autocomplete are supposed to carry over automatically, but the update doesn’t always apply cleanly, and the sudden name change alone causes a lot of “is this broken?” confusion.

Beyond the rebrand, autocomplete can also stop working for reasons that have nothing to do with it – backend connectivity, conflicting extensions, expired auth tokens, or a codebase large enough to choke the indexer. This guide covers both: what changed with Devin Desktop, and the underlying technical fixes that apply either way.

What Causes Windsurf Autocomplete Not Working

The Devin Desktop Rebrand: Windsurf became Devin Desktop as an over-the-air update – according to the official FAQ, it’s “the same IDE, same editor, and has the same features, but unified under the Devin brand.” Settings, extensions, keybindings, and pricing are supposed to migrate automatically with no action required. In practice, some users see autocomplete or Cascade (now rebranded Devin Local) toggle off during the transition and need to manually re-enable it once. The application binary also changed name from “Windsurf” to “Devin,” which can trigger corporate endpoint-management blocks if IT hasn’t pre-approved it.

Connection to AI Servers: Autocomplete depends on a live connection to Codeium/Devin’s backend. Outages, corporate firewalls, or an active VPN can silently block this without throwing an obvious error – chat may still work (since it uses a different pipeline) while inline autocomplete stays dead.

Extension Conflicts: Other AI autocomplete tools – GitHub Copilot, Tabnine, and similar – compete for the same inline-suggestion UI slot in VS Code-based editors. This is confirmed by real user reports: one developer found autocomplete broken specifically after uninstalling Copilot and installing Codeium/Windsurf, with leftover configuration from the old extension interfering with the new one even after reinstalling.

Authentication and Session Issues: Corrupted local auth tokens, a blocked browser redirect during login, a missing system keychain entry, or even system clock drift can all break the connection autocomplete needs, even though the editor itself opens normally.

Quick Fix – Try This First (30 Seconds)

Run through these before anything more involved – they cover the most common causes, including the rebrand-related ones.

Check what the app is actually called: If your Windsurf now opens as “Devin Desktop,” that’s expected. Go to Settings and confirm autocomplete/inline suggestions are still toggled on – the migration occasionally leaves it disabled.

Check server status: Visit status.codeium.com for any active incidents before troubleshooting locally.

Disable other AI extensions temporarily: If Copilot, Tabnine, or another autocomplete tool is installed, disable it and reload the window to rule out a conflict.

Note: if chat/Cascade (Devin Local) works fine but only inline autocomplete is dead, that points specifically to a connection or extension conflict rather than an account-wide outage.

Complete Step-by-Step Fix Guide

Work through these steps if the quick fix didn’t resolve it.

Step 1: Verify the Rebrand Migrated Cleanly

Open Settings and confirm your plan, extensions, and keybindings all look correct post-update. If anything looks reset, re-enable autocomplete manually under Settings > AI > Autocomplete. Note that the terminal command also changed from surf to devin-desktop, though the old command should still work during the transition period.

Step 2: Confirm Backend Connectivity

Check status.codeium.com for outages, then confirm your subscription is active under Settings > Account. If you’re on a corporate network or VPN, temporarily disable it to test, and if it resolves the issue, ask IT to allowlist the Codeium/Devin endpoints instead of leaving it disabled long-term.

Step 3: Remove Conflicting Extensions

Disable GitHub Copilot, Tabnine, or any other inline-completion extension. If you previously uninstalled one of these before installing Windsurf/Devin, its leftover settings can still interfere – try a full reinstall of the Windsurf/Devin extension after confirming the others are gone.

Step 4: Fix Login and Authentication

Sign out completely, clear stored credentials from your system’s keychain (Credential Manager on Windows, Keychain Access on Mac, or restart gnome-keyring-daemon on Linux), and sign back in – ideally in a browser session without extensions active, in case one is blocking the auth redirect. Also confirm your system clock is synced (NTP) since clock drift can invalidate auth tokens.

Step 5: Check File Permissions and Workspace Root

Confirm the editor has read/write access to your project files and that you opened the project from its actual root directory rather than a subfolder – autocomplete context can behave unpredictably otherwise.

Step 6: Reduce Indexing Load on Large Codebases

On large repositories, indexing can consume enough resources to delay or block suggestions. Create a .windsurfignore file in your project root (same syntax as .gitignore) and exclude heavy folders like node_modules and .git.

Step 7: Confirm Language and Credit Limits

Autocomplete works best on widely-used languages like TypeScript, Python, JavaScript, Go, and Rust – support can be thinner elsewhere. Also check Settings > Account for remaining free-tier credits, since autocomplete quietly stops once they’re exhausted rather than showing a clear error.

Advanced Fixes

Cascade/Devin Local not responding: if the AI chat agent times out on large requests, narrow its scope to a single file instead of the whole project, and check your browser/editor Developer Tools console for the actual error code behind a generic failure message.

Persistent performance issues: expect roughly 500MB-2GB of memory usage depending on project size – if that’s consistently maxed out, disabling other resource-heavy extensions alongside your .windsurfignore file usually helps.

Enterprise/managed devices: if the app suddenly won’t launch after the Devin Desktop update, check with IT – the binary name change from Windsurf to Devin can trip endpoint-management allowlists that were configured under the old name.

Still Not Working? Try These Instead

If autocomplete keeps failing after working through the steps above, these are worth trying while you sort it out.

Cursor – a VS Code-based editor with a similar inline-completion model and its own dedicated agent mode; see our Cursor error guide if you hit issues there.

GitHub Copilot – the most widely deployed alternative, with broad language support and native integration across most major IDEs.

Devin (the full agentic product Devin Desktop is now built around) – worth exploring directly if you want the autonomous-agent workflow rather than just inline autocomplete.

FAQ

Is Windsurf really gone now?

Not gone – rebranded. Following Cognition’s acquisition, Windsurf became Devin Desktop as an over-the-air update. It’s described as the same IDE and editor with the same features, just under the Devin brand, with existing settings and work fully preserved.

Do I need to do anything to migrate?

No manual migration is required for the update itself – it applies automatically. The one exception is managed/enterprise devices, where the binary name change from Windsurf to Devin may need IT approval.

Why did autocomplete work yesterday and not today?

Check first whether the app rebranded to Devin Desktop overnight and reset the autocomplete toggle in the process. If not, it’s most likely a temporary backend issue (check status.codeium.com) or a newly installed/updated extension conflicting with it.

What happened to Cascade?

Cascade is being rebranded as Devin Local, with the older Cascade name remaining available for a transition period. Functionality carries over rather than being removed.

Does the free tier still work the same way?

Pricing and plans are unchanged by the rebrand. If autocomplete stops working specifically on a free account, check remaining credits under Settings > Account before assuming it’s a bug.
