It's 2026 and I am still in the middle of porting our notes databases to web. Notes is still the main platform for our applications, we have around 50 or so. I have a lot of respect for what notes is and what it enabled developers to do and I try to bring some ideas of it to the platform I am building. Funny enough today is exactly the day I did the initial commit on the new project one year ago. Happy birthday to my platform i guess.

I was a Lotus Notes developer for more than 10 years. The speed at which you could develop useful software was mind-blowing. I started with Notes 4.5, IIRC, and ended my time around Notes 8.

The first few years were a little heavy on RAM usage, so people thought it was slow. To give you some context, this was back when 16 MB (megabytes, not gigabytes) of RAM was a thing. But as RAM increased, Notes was no longer a problem.

For example, Lotus Notes 8, which I still have on my personal PC, uses about 11 MB just after starting. Then it adds roughly 10 MB for each "app" you open. Today, Outlook alone uses around 170 MB just after starting.

It was incredibly powerful. And migrating a Domino server was incredibly easy. Basically, you just copied the DATA folder. I remember doing this when we migrated from Windows 2000/2003 to AIX.

In the same way, the Notes client was basically a portable app. You could just copy the NOTES and DATA folder, edit notes.ini, and have it running.

So sad to see it go.

That's crazy. I did a Notes migration to a custom Java/Red Hat platform 20 years ago, even at that time it was like "can't believe these guys are on Lotus Notes". I remember Howard Stern used to reference LN on his radio show in the early 90s.
