Heroku Docker GitHub Node.js hapi Vue.js AWS Lambda Amazon S3 PostgreSQL Knex.jsCheckly is a fairly young company and we're still working hard to find the correct mix of product features,price and audience.
We are focussed on tech B2B,but I always wanted to serve solo developers too.So I decided to make a $7 plan.
Why $7?Simply put,it seems to be a sweet spot for tech companies: Heroku,Docker,Github,Appoptics (Librato) all offer $7 plans.They must have done a ton of research into this,so why not piggy back that and try it out.
Enough biz talk,onto tech.The challenges were:
- Slice of a portion of the functionality so a $7 plan is still profitable.We call this the "plan limits"
- Update API and back end services to handle and enforce plan limits.
- Update the UI to kindly state plan limits are in effect on some part of the UI.
- Update the pricing page to reflect all changes.
- Keep the actual processing backend,storage and API's as untouched as possible.
In essence,we went from strictly volume based pricing to value based pricing.Here come the technical steps & decisions we made to get there.
- We updated ourPostgreSQLschema so plans now have an array of "features".These are string constants that represent feature toggles.
- TheVue.jsfrontend reads these from thevuexstore on login.
- Based on these values,the UI has simple
v-ifstatements to either just show the feature or show a friendly "please upgrade" button.
- ThehapiAPI has a hook on each relevant API endpoint that checks whether a user's plan has the feature enabled,or not.
Side note: We offer 10 SMS messages per month on the developer plan.However,we were not actually counting how many people were sending.We had to update our alerting daemon (that runs on Heroku and triggers SMS messages via AWS SNS) to actually bump a counter.
What we build is basically feature-toggling based on plan features.It is very extensible for future additions.Our scheduling and storage backend that actually runs users' monitoring requests (AWS Lambda) and stores the results (S3 and Postgres) has no knowledge of all of this and remained unchanged.
Hope this helps anyone building out their SaaS and is in a similar situation.
