SaaS with Feature Flags Stack
I used to deploy new features to all users and hope nothing broke. Now everything ships behind a flag — dark-launch to 1%, roll out to 10%, graduate to everyone with a kill switch always ready.
Public stack
I built my own newsletter platform instead of paying for Substack or Beehiiv. Costs about $15 a month in hosting, handles 8k subscribers, and I own the data and the brand completely.
Workflow stack
Payments infrastructure for the internet: card present and online processing, Billing for subscriptions and invoicing, Connect for marketplaces, Tax, Radar fraud tools, and Terminal for in-person hardware.
Open-core analytics, replay, flags, experiments, error tracking, warehouse, pipelines, and logs on PostHog Cloud—generous per-product free tiers each month, then usage-based rates (e.g. ~$0.00005/event for analytics after the first 1M events).
