1. App Hosting & Deployment
Vercel
What
Deploy Next.js, React, Astro, Svelte, APIs, serverless functions.
Why
Still the easiest deployment experience.
Free Tier
Very generous Hobby tier for personal projects, including serverless functions, web analytics, image optimization, and Git integration.([Vercel]{.underline})
Best workflow
GitHub → automatic deployments.
Limitations
Not ideal for heavy CPU workloads.
Worth in 2026?
Absolutely.
Fly.io
What
Tiny VMs worldwide.
Why
Great when serverless isn't enough.
Best workflow
Background workers.
Persistent services.
Long-running APIs.
Limitations
More DevOps.
Worth?
Yes.
Railway
One of the simplest ways to deploy:
-
PostgreSQL
-
Redis
-
Docker
-
APIs
Very fast prototype platform.
Coolify (self-host)
Worth knowing if you later rent a VPS.
2. Databases
Neon
What
Serverless PostgreSQL.
Why
Probably the best free SQL database today.
Free includes branching, autoscaling, and generous project limits.([Neon]{.underline})
Best workflow:
Backend
+
Prisma
+
Drizzle
+
Vercel
Turso
SQLite at the edge.
Excellent for:
-
personal tools
-
edge apps
-
AI agents
Much faster than people realize.
Convex
Not just a database.
Entire backend.
Realtime.
Functions.
Authentication.
Reactive queries.
Worth learning because it replaces several services.
MongoDB Atlas
Still useful.
Not as attractive as serverless SQL anymore.
3. Vector Databases
You already know:
-
Pinecone
-
Qdrant
Also learn:
Weaviate Cloud

Best workflow:
Upload once
Automatically resize
Generate thumbnails
Convert formats
Tigris Data
One of the most underrated object storage providers.
Strong free tier.
No egress pricing has made it popular with solo builders. ([Reddit]{.underline})
Supabase Storage
Still excellent.
5. Authentication
Clerk
Still my favorite.
Why?
-
OAuth
-
MFA
-
Organizations
-
User management
Almost zero backend code.
Better Auth
Open source.
Growing rapidly.

PostHog
Probably the best analytics platform.
Includes:
-
feature flags
-
experiments
-
funnels
-
session replay
Excellent free tier.
Mixpanel
Still excellent.
Very mature.
Umami
Privacy focused.
Simple.
7. Monitoring / Logging
Better Stack
Probably the best overall choice.
Includes:
-
uptime
-
incident alerts
-
logs
Grafana Cloud
Huge ecosystem.
Metrics
Logs
Tracing
Synthetic monitoring
Generous always-free observability tier with limited retention.([Grafana Labs]{.underline})
Sentry
Still essential.
Error tracking.
Performance.
Replay.
8. CI/CD
GitHub Actions
Still king.
Cloudflare Builds
Worth learning.
CodeRabbit
AI code review.
Huge productivity gain.
9. Edge / Serverless
Besides Cloudflare:
Deno Deploy
Fantastic.
Simple.
Fast.
Vercel Edge Functions
Excellent.
Netlify Edge
Still relevant.
10. AI APIs
These matter more than almost anything now.

Very affordable.
Cohere
Retrieval.
Embeddings.
Together AI
One API
Hundreds of models.
OpenRouter
One endpoint
Many providers
Great for experimentation.
Groq
Extremely fast inference.
Excellent free access for many workloads.
Cerebras
Ultra-fast inference for supported models.
Hugging Face Inference Providers
Gateway to many hosted OSS models without running them locally.
11. Developer Productivity
Trigger.dev
Background jobs.
Retries.
Scheduling.
One of the best services for replacing cron and queue infrastructure.
Free plan includes monthly credits, unlimited tasks, preview environments, and scheduling.([Trigger]{.underline})
Inngest
Alternative to Trigger.dev.
Resend
Transactional email.
Fantastic developer experience.
Novu

Coolify (for future self-hosting)
This stack minimizes local resource usage while covering hosting, databases, storage, authentication, AI, observability, and automation. It is also broadly aligned with what experienced solo founders report using successfully for low-cost production deployments in 2026. ([Reddit]{.underline})
