Anyone using LaunchDarkly, and willing to comment on the experience? Code-wise, this seems like a pretty straightforward problem. I'm surprised there aren't more competitors.

We use LD, because (1) we don't have time to make a pretty UI with user management and audit logs, and (2) we like the reliability story of running all of the heavy lifting through fastly's CDN.

They are a little more pricey than we'd prefer, but we're happy.

I've used it. I wasn't super impressed with the features around grouping accounts so that you can match a group with a feature toggle. As I recall, it was mostly regexes, rather then a long running group system. I'm guessing a big infusion of money will help with this.

Not to take away from the fact that this is a very useful tool, but every time I have wanted this, I have built it myself. My general strategy is to store flags in the user's data and for A/B testing, randomly assign A% of users to have a certain flag set. Then somewhere in the admin dashboard I'll drop a set of switches/buttons for activating flags and running A/B testing scripts. Collecting test results is simply m…

I saw this exact same sentiment when Optimizely was announced. Now, I cringe when people say they implemented their own A/B system (similar to what you wrote above). If you're running a business you probably need to spend your development efforts elsewhere.

Feature Flags FTW!

Pretty much. The issue now is, can I implement feature flags faster than I can implement the LaunchDarkly API? I think I can do feature flags faster.

This is exactly why they slightly pivoted to serving business teams.

In general, I'd say most tech businesses are aware of Optimizely and the value proposition is quite compelling. I certainly wouldn't try to save money on our Optimizely spend by building any part of their system myself. But if I could save the company $700/month (the price for 50k MAU, which doesn't even cover our requirements) by implementing something as simple as feature flags, I'd add it to our development roadmap. For smaller companies, ~$10k a year is not trivial.

However, I acknowledge that I may be vastly oversimplifying, and am not knowledgeable enough about LaunchDarkly to speak so brazenly about how I could do it myself. My main point is that as a small web development company, we have this feature in our builds already, and it only cost us a couple hours of development time to implement it.

This is just aimed at SaaS web offerings right?

We have mobile (iOS/Android) SDKs, so you can use LD for mobile apps as well, but the backend SDKs are primarily meant for SaaS-style server processes (where the SDK token can be guarded from users, and the process serves many different users, some of whom will get different flag values).

We have gotten some requests for desktop SDK support, which would work more like the mobile or JS clients work, since there is a single user at a time, and the key used to get flag values must not leak any proprietary business info or details about other users. This is on our roadmap, so the funding will help here :)

Initially, I was very confused about why this is a good idea. Before the web, feature "productization" was the always part of design of the system and of each module: in other words, each feature should be disabled based on some criteria (i.e., like not ready for release, insufficient licenses), measured, etc.

But then after a few minutes... I kinda got it. I think this is a great tool for marketing, biz, and product management in organizations where the overall organization structure is kinda messed up and they cannot convince development to do things right. Which is 90% of companies. Very similar to hiring external management consulting services: since nobody in the company is capable to organize this.

So in short - LaunchDarkly will do well.
