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
Add enterprise SSO, SCIM provisioning, and audit logs to your SaaS product without building it in-house. The identity features enterprise procurement teams require before signing a purchase order.
Workflow stack
Enterprise identity
SSO with SAML 2.0 and OIDC, automated SCIM user provisioning from corporate directories, MFA enforcement, and SOC 2 compliance documentation that enterprise security teams actually accept.
Open tool profileUser and audit data
Application-level user data, permission records, and audit logs stored in Postgres — Auth0 handles identity, your database handles everything the business logic needs.
Open tool profileEnterprise billing
Invoice-based billing for annual contracts, custom pricing per account, and usage-based add-ons — the billing portal handles self-serve tier upgrades between contract renewals.
Open tool profileObservability
Full APM, infrastructure metrics, and log aggregation in one platform — SOC 2 auditors want proof of monitoring and Datadog's audit trail satisfies that requirement cleanly.
Open tool profileError tracking
Application error monitoring with PII scrubbing configured — enterprise customers ask what data leaves their environment and Sentry's data scrubbing rules answer that question directly.

I run five side projects on one DigitalOcean Droplet for $24 a month. This stack handles 80k monthly visitors combined and has taught me more about infrastructure than years of managed platforms ever did.
Production Python backend for AI-powered applications — designed for the async I/O, complex dependencies, and long-running inference jobs that come with serving language models at real traffic.
PostgreSQL uses the PostgreSQL License (liberal, BSD-style)—$0; RDS, Cloud SQL, Neon, Supabase, etc. bill for compute and storage (postgresql.org, March 2026).
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.
Unified observability: infrastructure monitoring, APM, logs, RUM, synthetics, security, and more—sold as modular products that share dashboards and agents.
Error monitoring, performance tracing, logs, session replay, profiling, and uptime products for developers—SDKs across major languages and frameworks with issue workflow at the center.
