5 best feature-flag tools for Haskell
When it comes to managing feature rollouts in Haskell applications, feature flags are indispensable. They allow developers to experiment and deploy with confidence. However, the variety of available feature-flag solutions can make it tough to choose the right one. In this article, we’ll compare the top 5 feature-flag solutions for Haskell developers, considering pricing, ease of use, and the most valuable features each service offers.
Our top pick#1 Tggl.io
Tggl leads our list, offering a great balance of ease of use and rapid Haskell integration, which can be accomplished with just a single API call.
Features
Tggl offers all the essential features you’d expect from a feature flag service, even in its most affordable plan. This makes it an excellent starting point for developers or teams who are new to feature flagging or working with a limited budget. You can easily manage your feature rollouts, conduct A/B tests, plan release dates in advance, and toggle features without needing to upgrade to a higher tier. You get unlimited feature flags and basic monitoring out of the box.
As your requirements become more complex, Tggl’s higher-tier plans offer advanced features such as in-depth analytics, flag change reviews, and server side flag evaluation, giving you more control and insights.
Ease of use
Tggl takes the top spot in our comparison because it’s particularly easy to use. The setup process is streamlined, and the interface is designed with usability in mind. To give you a practical example, we recorded a short video where we enable a flag for 20% of French users. Similar recordings were made for all the tools in this list, allowing for an objective comparison of their ease of use.
The video demonstrates how easy it is to use Tggl, highlighting its user-friendly nature. To further assess its usability, we collected user ratings for both ease of use and setup time. These ratings provide real-world feedback from developers who have worked with Tggl.
- Setup time: 4.8/5
- Ease of use: 4.9/5
Pricing
To wrap up, Tggl is the most budget-friendly option on our list, with a starting price of €180/yr for up to 5 seats. Smaller teams will find that costs are manageable, as they are based on the number of seats and request volumes. For larger teams, Tggl offers a flexible pricing model where you can have unlimited seats and only pay for the number of requests.
- Price for 5 seats: €180/yr
- Price for 10 seats: €530/yr
