Pricing & Plans

Comparing prices could be difficult since all the feature flags services have different pricing models. So I have created 4 imaginary companies of different sizes with different needs.

1. Hobby Project:

Low budget. 1-3 team members, 1-10 feature flags, small amount of users / traffic.

2. Startup:

Some budget, but still want't to keep it simple. 3-20 team members, 10-100 feature flags, varied number of users / traffic.

3. Established Business:

Higher budget, but no surprises. 20-100 team members, lots and lots of feature flags. Lots and lots of users / heavy traffic.

4. Enterprise

Possibly requires the highest plan of all with custom solutions. Price is usually not the issue here.
