Another tool to the list - Outsystems?

My New Year resolutions:-  

  1. Learn some new stuff.
  2. Finish my personal projects (Arcade, game development and writing).
  3. Try and get better at golf!
Let's kick off #1 :-)

Revisiting Outsystems: Free Developer Tier and Familiar Parallels

I’ve been experimenting with Outsystems on and off for a while.

  • First tried it back in 2019.

  • Revisited in March 2025.

  • Challenges: environments only lasted 10 days (though there were workarounds), and everything was in a shared space—meaning my work was visible to other newcomers. At one point I even accidentally updated someone else’s tutorial models!

Hot News

As of October 1, 2025, Outsystems now offers a 100% free developer tier that doesn’t expire. Even better, it’s your own private environment—not shared. As long as you revisit it periodically (no exact timeframe specified), your training instance will remain available.

This feels like the right time to revisit the technology, both personally and professionally.

Pricing Caveat

Once you move beyond the free tier, Outsystems is priced for enterprise use. The entry point is around $36k, with additional costs for resources, capacity, user counts (internal and external), and multiple applications. Think of it as a pricing model similar to Salesforce. If you’re coming from Synon or Plex, the structure will feel familiar.

Observations While Exploring

1. Community Energy The Outsystems community reminds me of the old Synon days in the mid-90s. Take a look at the conference highlights reel. I remember attending Synon Europe in London around 1997, with Vigil on stage talking about advanced patterns. The energy in the room was incredible, and it looks like Outsystems developers are experiencing that same buzz today.

2. Architectural Parallels The concepts, approach, and terminology in Outsystems development tools feel very familiar to anyone from the 2E and Plex ecosystems. I’d even hazard a guess that there’s some crossover of ideas. You can see more in their evaluation guide.

Looking Ahead

I’ll continue exploring Outsystems and share direct comparisons to Synon 2E and Plex where appropriate. Some tutorials (like the Horse Racing Model) aren’t available, but overall I’m impressed with what I’ve seen so far.

Subscribe to the blog for updates, or follow the Outsystems label. After this, I may also look at other low-code platforms—Appian, Salesforce, Mendix—and see how those ecosystems align.

Synon 2E internal file structure

I have a few posts (see below) where I discuss the Synon 2E internal files.


This all stems from the awesome work presented by this legend, Steve!!!

Warning query these files at your own peril!  However, this knowledge is awesome for things like generation of data dictionaries and source code pre-compilations.

This blog isn't the only useful place to get great Plex and Synon 2E content.

Here are some 'up to date' and 'active' links.  

These appear to be creating content largely from the 2E manuals.

Synon 2E - Technical Deep Dives

Synon 2E - Technical Deep Dives

Below are some long form posts targeting specific areas of the Synon 2E tech stack.

I thoroughly enjoyed writing these 'back in the day' and hope that they help some of you.

The generic data driver is a method to output *Arrays into PRTFIL's or DSPFIL's without having to define a structure file etc.  Very, very useful and I have used numerous times.  The only design consideration is the array size depending on which RPG generator is being used. 


Performance tuning batch jobs?


Pet hates?

Some things that I don't like seeing in 2E coding.  Call them standards?, call them being a fusspot?

Code reviews, love them or hate them, they share knowledge and create better developers.

General Synon 2E topics, hints, tips, 'How to' guides.  They'll be a gem or two in here for most of you.

This should be standard in all shops

Nice little tips here

A personal favourite

Really useful, especially with the new webservices push and unpack and package up input and output arrays.
