Features
More than a log channel.
Collection, storage and delivery are separate, so you can keep a complete history without publishing every single event.
Context survives
Edits and deletions with the original text and attachments, thanks to encrypted snapshots.
Every event in its place
One channel for bans, one for messages, mentions only where needed. Filters for users, roles and channels.
Search and export
Filter by event, actor, target, channel and time range. Export to JSON when investigating an incident.
Role-aware dashboard
Discord sign-in with Viewer, Moderator, Admin and Owner levels verified live against the server.
Keep only what you need
Global or per-event retention, plus deletion of a user’s data on request.
Pipeline
From event to channel, nothing lost.
- 01
Discord Gateway
The bot receives the event and resolves the actor from the Audit Log.
- 02
Encrypted history
The event is stored before delivery: a failed send never deletes anything.
- 03
Filters & routing
Destination channel, exceptions, mentions and embed customisation are applied.
- 04
Log channel
The embed lands in the chosen channel; failed attempts stay visible in the dashboard.
Getting started
Up and running in three steps.
- 01
Add the bot
Authorise Sentinel with read and log-delivery permissions only: no moderation rights.
- 02
Sign in with Discord
The dashboard lists the servers you can manage and applies your access level.
- 03
Choose what to record
Enable loggers, pick channels and retention. Every panel change is audited.
Security
Built so it cannot do damage.
A logging bot sees a lot. Sentinel is designed so that, even if compromised, it cannot moderate and cannot easily exfiltrate.
- Read-only
- An internal policy blocks bans, kicks and changes to roles, channels and messages, regardless of Discord permissions.
- Encrypted data
- Message content, attachments and event details are encrypted with AES-256-GCM at rest.
- Separated secrets
- The bot token never reaches the web panel; every service has its own credentials.
- Least-privilege database
- The bot cannot read sessions or panel audit; distinct Postgres roles for API and bot.
- Segmented network
- Database and Redis are never exposed; each container only reaches what it needs.
Open source
The code is open. Check it.
A bot that reads your server should be verifiable. All of Sentinel — bot, dashboard and deployment scripts — is public on GitHub under the AGPL-3.0 licence.

FAQ
Everything you need to know.
How can I see deleted messages on Discord?
Discord does not keep deleted messages. Sentinel stores an encrypted snapshot of every message when it is sent, so when it is edited or deleted your log channel shows the original text, the author and the attachments.
How do I find out who banned, kicked or timed out a member?
Sentinel matches every event with Discord’s Audit Log and shows the moderator who did it, the target and the reason — for bans, kicks, timeouts, roles, permissions, channels and webhooks.
Does Sentinel need administrator permissions?
No. It only needs to read channels, view the Audit Log and post in your log channel. An internal policy blocks every moderation action, whatever role the bot has.
Is Sentinel free?
Yes: the Free plan includes every standard logger. Plus, Pro and Brand add high-volume loggers, longer history and higher limits. The code is open source, so you can also host it yourself.
Where is my data stored?
In a PostgreSQL database, with message content and event details encrypted with AES-256-GCM. You choose how long it is kept and can delete a user’s data on request.
