Open Slack in your browser and navigate to a DM, group, or channel.

Note: This extension deletes only your own messages, and deletion is permanent.

I built this plugin as a free and open-source contribution to the community. Most similar tools lock useful functionality behind paywalls, so I wanted to make something that includes many of the premium features people usually have to pay for - without subscriptions, tracking, or hidden catches.

If you find this useful, that means a lot. And if there’s a feature you feel is missing, run into a bug, or have suggestions for improvements, feel free to reach out at [email protected] - I’d genuinely love to hear feedback and keep improving it.
