[Windows] Web UI not showing sessions - path separator mismatch (backslash vs forward slash) #21340
Description
Description
On Windows, the Web UI does not display session history, while the Desktop version works correctly.
Root Cause Analysis
After investigation, I found that the issue is caused by path separator mismatch between the database storage and Web API queries:
| Component | Path Format | Example |
|---|---|---|
| Database (sessions.directory) | Backslash \ |
C:\Users\zhangqianfeng |
| Web API query | Forward slash / |
C:/Users/zhangqianfeng |
API Test Results
# Query with backslash (Windows native) - WORKS
GET /session?directory=C:\Users\zhangqianfeng&roots=true&limit=55
→ Returns 11 sessions ✅
# Query with forward slash (Web UI format) - FAILS
GET /session?directory=C:/Users/zhangqianfeng&roots=true&limit=55
→ Returns 0 sessions ❌
The data exists in the database, but Web UI queries with forward slashes fail to match the backslash-stored paths.
Environment
- OpenCode version: v1.3.17
- OS: Windows 11
- Terminal: PowerShell / Windows Terminal
Steps to Reproduce
- On Windows, create sessions using Desktop app or CLI
- Open Web UI (localhost:4096)
- Sessions are not displayed in the sidebar
- Desktop app shows all sessions correctly
Expected Behavior
Web UI should display all sessions that exist in the database, regardless of path separator format.
Actual Behavior
Web UI shows empty session list because path matching fails.

- The web version does not display chat history. #20165 - Web version does not display chat history
- [Web UI] Sessions under workspace root are missing after upgrading to 1.2.21 #16744 - Sessions missing after upgrade
Suggested Fix
The API should normalize path separators before querying/matching, converting both \ and / to a canonical format.
Workaround
- Use Desktop version (reads local data directly, bypasses the path matching issue)
- Or access sessions directly via URL:
http://localhost:4096/session/{session_id}

Same bug, I have never been able to see the session list on Windows. I thought it was designed that way. It wasn't until one day when I used it on Ubuntu that I saw a clear session list panel. Then I knew they must have made a mistake on Windows.

I’m having a similar issue in some ways. I can’t see the session list on Windows — not even sessions I’ve just created under the same project in the same web service show up. The local version is 1.14.24, while the web UI shows OpenCode Desktop v1.14.23. Maybe I need to switch to WSL to check if it’s the same problem…
2026-05-01 now it works fine

I can confirm this still reproduces on Windows with OpenCode
1.14.28.Environment
1.14.28opencode webSymptom
Evidence
The sessions are being persisted. In the local OpenCode database, I can see unarchived root session rows for the affected project:
parent_id IS NULLtime_archived IS NULLdirectoryis stored using a Windows backslash path formatSo this does not look like browser storage loss. It looks like the Web sidebar/session loader is failing to list/render sessions that already exist, likely due to directory/path matching or project-context mismatch.

Has anyone found a workaround while using opencode web on windows? I noticed that git worktree folders do seem to work fine, but the main repo folder does not show sessions.

Cross-referencing: A new report (#29071) documents the same underlying issue —
session_directory_filter_enableddefault + path resolution mismatch between Desktop and CLI causing sessions to be hidden, with a workaround ("session_directory_filter_enabled": falsein kv.json).wlclass commentedon Jun 1, 2026
This problem has existed for a long time and it is the most painful aspect for me.

Fixed in v1.16.0 by #29666.
Path separators are now handled at the database boundary: session/project path columns are Drizzle custom types (
packages/core/src/database/path.ts) that store forward slashes on Windows and normalize query parameters bound ineq(), so/and\forms of the same path match the same rows. A one-time migration (20260601010001_normalize_storage_paths) rewrote existing backslash rows.Please upgrade to >= v1.16.0. If the session list is still wrong on a current release, comment with
opencode --versionand a sampledirectoryvalue from thesessiontable and we will reopen.
