<Tip>
  You can ask OpenCode to debug itself. Describe the problem and ask it to use this troubleshooting page; it can read the
  steps below, inspect its service and logs, and help identify the issue.
</Tip>

OpenCode runs as two processes: the TUI is a client, while a background server owns sessions, plugins, permissions, and
other application state. Start by determining whether an issue is in the client, the shared server, or a specific project.

## Check the background service

Show the current server status:

```bash
opencode2 service status
```

Verify that its API is healthy:

```bash
opencode2 api get /api/health
```

If the service is stuck or unhealthy, restart it:

```bash
opencode2 service restart
```

From inside the TUI, run `/reload` to restart the managed service and reconnect:

```text
/reload
```

You can also stop and start it explicitly:

```bash
opencode2 service stop
opencode2 service start
```

<Note>
  OpenCode normally discovers or starts the shared background service automatically. The service commands are only needed
  when diagnosing its lifecycle.
</Note>

## Run an isolated session

Use standalone mode to run the TUI with a private server that exits with it:

```bash
opencode2 --standalone
```

If an issue disappears in standalone mode, it is likely related to the shared background service rather than the TUI or
project itself.

## Inspect the API

The `api` command uses the same discovery and authentication flow as the TUI. It accepts either an HTTP method and path or
an OpenAPI operation ID.

See the [API reference](/api) for all endpoints and operation IDs.

Pass a JSON request body with `--data` or `-d`, and add headers with `--header` or `-H`.

<Warning>
  Running `opencode2 api` may start the background service when no compatible healthy service is available.
</Warning>

## Read logs

Installed builds write logs to:

```text
~/.local/share/opencode/log/opencode.log
```

Follow the log while reproducing the problem:

```bash
tail -f ~/.local/share/opencode/log/opencode.log
```

Each line includes a process `run` ID and a `role` field. Use `role=cli` for TUI and command startup, and `role=server` for
session, provider, plugin, permission, and tool activity.

```bash
grep 'role=cli' ~/.local/share/opencode/log/opencode.log
grep 'role=server' ~/.local/share/opencode/log/opencode.log
grep 'run=8fc3b1d5' ~/.local/share/opencode/log/opencode.log
```

Increase verbosity for one reproduction:

```bash
OPENCODE_LOG_LEVEL=DEBUG opencode2
```

## Service files

The shared server registers itself at:

```text
~/.local/state/opencode/service.json
```

Its private service configuration is stored separately at:

```text
~/.config/opencode/service.json
```

The database normally lives at:

```text
~/.local/share/opencode/opencode-next.db
```

`OPENCODE_DB` can override the database location.

<Warning>
  Do not delete or edit service files or the database while troubleshooting. Use the service commands to manage the daemon,
  and make a backup before inspecting persistent data with external tools.
</Warning>

## Explicit servers

When connecting with `--server`, set `OPENCODE_PASSWORD` if the server requires authentication:

```bash
OPENCODE_PASSWORD=secret opencode2 --server http://127.0.0.1:4096
```

The CLI checks the server before opening the TUI and reports whether it is unreachable, requires a password, or rejected
the supplied password.

## Report an issue

Include the following when reporting a reproducible problem:

- Output from `opencode2 --version`
- Output from `opencode2 service status`
- The smallest sequence of steps that reproduces the issue
- Whether the issue also occurs with `opencode2 --standalone`
- Relevant log lines, including their `run` and `role` fields

Remove API keys, authorization headers, prompts, file contents, and other sensitive data before sharing logs.

## Local development

When working from the OpenCode repository, run V2 commands from the repository root:

```bash
bun dev
```

The local development channel keeps its logs, SQLite database, and service registration separate from installed builds:

```text
~/.local/share/opencode/log/opencode-local.log
~/.local/share/opencode/opencode-local.db
~/.local/state/opencode/service-local.json
```

Use the same diagnostics through the package development command:

```bash
bun dev service status
bun dev service restart
bun dev api get /api/health
```
