Redis / Valkey

Pro

DevDb connects to Redis and Valkey servers. It shows keys by namespace and has a command console.

Connect

From the panel

1. Under Remote Connections, click Add, then select Redis / Valkey.
2. Enter the details:

Field	Default	Description
Host	localhost	Server host
Port	6379	Server port
Username	—	ACL username. Leave empty for the default user.
Password	—	Password
DB Index	0	Database number
Key Prefix	—	Show only keys that start with this prefix, for example app:
TLS	Off	Connect over TLS

Or paste a connection string: redis://user:pass@host:6379/0, or rediss://... for TLS.

3. Click Test, then click Connect.

From .devdbrc

[
  {
    "name": "Local Redis",
    "type": "redis",
    "host": "127.0.0.1",
    "port": 6379,
    "database": 0
  }
]

See the Redis reference for all keys.

Browse keys

• DevDb groups keys by namespace: the part of the key before the first :. For example, user:42 is in the user namespace.
• DevDb reads keys with SCAN. It does not use KEYS, so it does not block the server.
• On large databases, DevDb stops counting after 50,000 keys and shows an estimate.
• Hashes, lists, sets, sorted sets and streams show one row for each element. DevDb loads large values in pages.

Edit data

You can edit values, set values to null, and delete rows from the table view. DevDb collects the changes in an edit session. Press Cmd+S / Ctrl+S to save. See Edit data.

Command console

The console sends Redis commands to the server (RESP). Type a command, then press Enter or click Run:

GET user:42
HGETALL session:abc
TTL cache:home

You can also send a JSON array: ["SET", "greeting", "hello world"].

Write confirmation

DevDb runs read commands (for example GET, HGETALL, SCAN, TTL, INFO) immediately.

For all other commands, DevDb shows the command and asks you to confirm before it sends it. This includes commands that change data (SET, DEL, EXPIRE) and admin commands (FLUSHALL, CONFIG SET). Click Run command to send it. Click Cancel or press Esc to discard it.

Cancel

While a command runs, DevDb shows a bar with a Cancel button. Click it to stop waiting for the result.

MCP

MCP clients can run Redis commands through the MCP server. By default, DevDb accepts only read commands from MCP clients.

Troubleshooting

• WRONGPASS or NOAUTH: the username or password is not correct. See Troubleshooting.
• Connection refused: the host or port is not correct, or the server does not accept remote connections.
• TLS errors: for a managed service, turn on TLS or use a rediss:// URL.
