App limit on a single Heroku account

Is there a limit to the number of apps I can host with a single Heroku account?

I currently run multiple apps each using 1 dyno for free. But could I host hundreds (or even thousands) of small applications for free?

I also know there is a 2TB bandwidth soft limit, but is there any other limitation I could encounter?

How many apps can you have on Heroku?

Verified accounts can create no more than 100 apps.

How many apps can I create for free with Heroku?

A 'Free' tier Heroku account allows up to 5 apps.

How many requests per second can Heroku handle?

These may be conducted without any need for approval from Heroku, so long as they're limited to 10,000 requests/second for any given application. This applies to all regions for the Common Runtime.

How many dynos are free on Heroku?

Personal accounts are given a base of 550 free dyno hours each month. In addition to these base hours, accounts which verify with a credit card will receive an additional 450 hours added to the monthly free dyno quota.

A clear answer surfaced in the Heroku July 2013 newsletter about platform limits. The maximum number of apps per account is 100.
