Best Free Tiers for Developers in 2026: SaaS, PaaS & IaaS Tools

The free-tier landscape shifted hard between 2023 and 2026. Heroku killed its free dynos in November 2022, PlanetScale dropped its Hobby plan in early 2024, and Fly.io quietly replaced its always-free allowance with a $5 monthly credit. A lot of “free tier” advice from older blog posts now points at services that will charge you the moment your card is on file.

We rebuilt our reference list from scratch in 2026, cross-checking the free-for-dev community catalog against each provider’s current pricing page. What survived is genuinely useful for side projects, MVPs, and learning — as long as you know where the cliffs are.

Hosting, Edge, and Compute

For a typical Node, Next, or Astro side project, three platforms still cover almost everything for $0:

• Vercel Hobby — 100 GB bandwidth, unlimited static requests, 1 million Edge Function invocations, 100 deployments per day. Personal use only; commercial work requires Pro at $20/month per seat.
• Netlify Free — 100 GB bandwidth, 300 build minutes, 125k serverless function invocations. No commercial-use restriction, which makes it the safer default for a portfolio site that runs ads or affiliate links.
• Cloudflare Pages + Workers — unlimited bandwidth, 500 builds per month, 100k Worker requests per day on the free Workers plan. The bandwidth ceiling is the headline: a Hacker News spike won’t bankrupt you the way it might on a metered platform.

For long-running processes (Discord bots, queue workers, websockets), the picture is grimmer. Fly.io now bills from the first minute beyond the $5 credit, Railway ended its hobby-free plan in 2023, and Render’s free web service spins down after 15 minutes of inactivity with a 30+ second cold start. If you need a 24/7 process, an Oracle Cloud Always Free Arm VM (4 vCPU, 24 GB RAM split across instances) remains the most generous offer on the market — assuming you can stomach Oracle’s account verification flow.

Databases, Auth, and Backend Services

Managed Postgres is where the free-tier market has gotten genuinely good:

• Supabase Free — 500 MB database, 1 GB file storage, 50k monthly active auth users, two projects. Inactive projects pause after seven days, which trips up demos but is one click to wake up.
• Neon Free — 0.5 GB storage per branch, autoscaling compute that scales to zero, full branching included. Scale-to-zero means a ~500 ms cold start on the first query after idle, but you pay nothing while the database sleeps.
• Turso Free — 9 GB total storage across up to 500 databases, 1 billion row reads per month. Useful when you want SQLite-per-tenant rather than one shared Postgres.

For caching and queues, Upstash gives you 10,000 Redis commands per day and a generous QStash allowance on the free plan, billed per request rather than per hour. MongoDB Atlas still offers a 512 MB shared M0 cluster — enough for a CRUD prototype but tight for anything with serious indexes.

Auth has gotten cheaper too. Supabase Auth (bundled with the database tier), Clerk’s free plan (10k MAU), and Auth0’s free plan (25k MAU after their 2024 expansion) all cover the realistic user count of a pre-launch product. Pick on developer experience, not on price.

CI/CD, Monitoring, and AI APIs

GitHub Actions remains the default and the most generous: 2,000 minutes per month on private repos, unlimited on public repos, with Linux runners free. For larger matrices, Buildjet and BuildKite both offer free hobbyist tiers that beat Actions on raw CPU per minute.

For observability, the situation is mixed:

• Sentry Free — 5,000 errors, 10k performance events, 50 session replays per month, single user. Hits the free cap fast on any real traffic.
• Grafana Cloud Free — 10k Prometheus metric series, 50 GB logs, 50 GB traces, 14-day retention. The most generous free observability stack on the market right now.
• Better Stack Free — 10 monitors, 3-month log retention, 30-second checks. Better starting point than UptimeRobot if you also want logs alongside uptime checks.

AI APIs are the toughest category. OpenAI removed new-account free credits in 2024. Anthropic offers limited trial credits on signup that vary by region. Google’s Gemini API has a free tier with strict per-minute rate limits. Groq’s free tier is the standout for low-latency Llama and Mixtral inference — generous request quotas, no card required at signup.

When the Free Plan Stops Making Sense

The cost of staying free is usually invisible until something breaks. We watched a project sit on Supabase Free for nine months, then lose two days debugging a paused-database connection error after a long weekend. The fix was a $25/month upgrade that should have happened at month three.

A few signals that you’ve outgrown the free tier:

• You’re architecting around quotas (batching writes, caching aggressively) instead of around your product.
• You can’t share the project with a teammate because the free plan is single-user.
• You’re spending more than an hour per month working around platform limits.
• Your project is generating any revenue at all — most “personal use” free tiers prohibit commercial workloads.

The honest math: a typical indie project on Vercel Pro ($20), Supabase Pro ($25), and Sentry Team ($26) runs $71/month. That’s less than one hour of contractor time. If your project clears that bar in value or revenue, paying is the cheaper option, not the more expensive one.
