Convox has the same goal of a PaaS: to give you and your team an easy way to focus on your code and never worry about your infrastructure.
One big difference with Convox is that we accomplish this with single-tenant AWS things. You and your team's deployment target is an isolated VPC, ECS (EC2 container service), and ELB (load balancers).
If you're asking for a cost comparison, we're building Convox to be extremely cost competitive by unlocking AWS resource costs for everyone.
Its easiest to compare the cost of memory across platforms, though not always apples to apples...
The base Convox recommendation is 3 t2.smalls which is 6 GB of memory which costs about $100 / month. If your app can be sliced up into 512 MB processes, you can easily run 10 processes, which could be 2 to 5 medium traffic PHP apps on the cluster.
I'm finding PagodaBox pricing calculator a bit confusing but 6 512 MB processes, so 3 GB of memory, is $189.
Do you plan to eventually charge a monthly fee for using the command-line tool?
The most straightforward model, and where we are already making some money, is running a Convox as a managed service.
In this setup you and your team get Convox API keys. Convox installs, runs and updates everything for you in our accounts. You get a monthly bill that's your AWS resource costs plus a percentage to Convox for management.
We will be tweaking this model to sell packages so bills are really easy to understand.
Some other experiments we're doing...
We sell support packages and professional services for app setup, migration and custom feature development.
We have a per-seat model for productivity features. Private GitHub repos and Slack integrations are $19 / user / month. There are more closed SaaS tools like this coming.
Infra is trending to commodity prices industry wide.
We'll be selling SLAs, support, productivity tools on top of that infra.
You'll get a cutting edge private platform without hiring and managing your own devops team to build and maintain it.
Open source users will help grow the user base and make the platform better without us running a freemium platform.
