PostHog — Free Product Analytics Suite
Free forever
Product analytics, session replay, feature flags, error tracking and surveys in one open-source platform.
What's free: Monthly free allowances that reset every month: 1M analytics events, 5,000 session recordings, 1M feature-flag requests, 100K exceptions and 1,500 survey responses.
No card required
For: Developers
Allowances are per product and reset monthly; exceeding them moves you to paid usage pricing. Generous enough to run a real early-stage product on $0.
Netlify — Free Plan
Free forever
Deploy websites and web apps with previews, custom domains, SSL, functions, database and blob storage.
What's free: $0-forever plan metered in credits: 300 credits/month covering production deploys (15 credits each), compute (10 credits/GB-hour), bandwidth (20 credits/GB) and requests (2 credits per 10k). Unlimited deploy previews, custom domain + free SSL, serverless/edge functions, Netlify DB and Blobs included.
No card required
For: Developers
Hard cap — when the 300 monthly credits run out, the site pauses until the next cycle or an upgrade. Credit-based pricing replaced the old fixed quotas, so check the meter before a launch spike.
Vercel — Hobby Plan
Free forever
The deployment platform behind Next.js — hosting, serverless functions and edge network for personal projects.
What's free: $0 Hobby plan: 100 GB data transfer, 1M function invocations, 1M edge requests, 4 hours of active CPU/month and 5,000 image transformations.
No card required
For: Developers
Hard limits — hitting one pauses that feature (roughly 30 days); there is no overage billing on Hobby. Hobby is for personal, non-commercial use only; commercial projects need Pro.
Cloudflare Workers — Free Plan
Free forever
Serverless code at the edge, plus KV storage, D1 SQL database and free unlimited static-asset hosting.
What's free: 100,000 requests/day and 10 ms CPU per request on Workers; KV with 100k reads/day and 1 GB storage; D1 with 5M rows read/day and 5 GB storage; static assets served free and unlimited.
No card required
For: Developers
Daily quotas reset every 24 hours; exceeding a quota returns errors rather than bills. Per-request CPU is capped at 10 ms on the free plan.
Supabase — Free Plan
Free forever
Open-source Firebase alternative: Postgres database, auth, file storage, realtime and edge functions.
What's free: 500 MB database, 50,000 monthly active users for auth, 1 GB file storage, 5 GB egress, 500K edge-function invocations/month, unlimited API requests, up to 2 active projects.
No card required
For: Developers
Free projects are paused after 1 week of inactivity (restorable from the dashboard) and have no automatic backups. Best for prototypes and side projects, not always-on production.
Convex — Free Plan
Free forever
A reactive backend-as-a-service with a TypeScript-first database and server functions built in.
What's free: 1M function calls/month, 0.5 GB database storage and 1 GB file storage, for teams of up to 6 developers — with no inactivity pausing.
No card required
For: Developers
Free is a hard cap — no pay-as-you-go overage. The paid Starter plan ($0 base + usage) is where overage starts, and it requires a card.
Clerk — Hobby Plan
Free forever
Drop-in user authentication and user management for web and mobile apps.
What's free: Free up to 50,000 monthly retained users per application, unlimited applications, 3 back-office seats and custom domains.
No card required
For: Developers
The free allowance counts “retained users” (users active in consecutive months), not raw sign-ups. Beyond 50,000 MRU you move to paid pricing.
LaunchDarkly — Developer Plan
Free forever
Feature flags and release management, with a genuinely free entry plan.
What's free: $0-forever Developer plan: unlimited seats and feature flags, 5 service connections, 1,000 client-side MAU/month, 5,000 AI config runs/month, 10M logs + 10M traces/month, 1 project with 3 environments, 14-day data retention.
No card required
For: Developers
One project only, and event/MAU allowances are sized for small apps and evaluation rather than production scale.
Liveblocks — Free Plan
Free forever
Collaboration infrastructure — presence, comments, notifications and multiplayer sync for your app.
What's free: A permanent free plan covering up to 100 monthly active users, with per-feature monthly caps (e.g. 2,000 comments/month) across presence, storage, comments and notifications.
No card required
For: Developers
Hard caps per feature; the free plan requires keeping a “Powered by Liveblocks” badge. Treat it as a prototyping and small-project tier — plan a paid tier before any commercial launch.
MongoDB Atlas — M0 Free Cluster
Free forever
A managed MongoDB database cluster that costs nothing, forever.
What's free: M0 cluster, free forever: 512 MB storage, shared RAM/vCPU, up to ~100 operations/second — enough for learning, prototypes and tiny apps.
No card required
For: Developers
No backups on M0, shared-tenancy performance and a very small scale ceiling; clusters can pause after prolonged inactivity. One M0 per project.
Apify — Free Plan
Free forever
Cloud platform for web scraping and automation “actors,” with a large public actor store.
What's free: $5 of platform usage credit every month on the free plan — enough to run small scraping and automation jobs each month.
No card required
For: Developers
Hard stop: when the $5 is used up, jobs stop until the next cycle; unused credit does not roll over.
Databricks — Free Edition
Free forever
The lakehouse and data-AI platform in a free, self-serve edition for learning and experimentation.
What's free: A permanent free workspace: serverless compute, notebooks, SQL and data/AI tooling — no cloud account contract and no payment method involved.
No card required
For: Developers
Daily usage quotas — when you hit them, compute pauses until the next day. Serverless only (no GPUs, no custom compute). Positioned for learning and non-commercial experimentation, not production workloads.
Cloady — Free Cloud Workspace
Free forever
A hosted cloud IDE and workspace you can run real projects in, with a true free tier.
What's free: One free workspace per account: 0.5 vCPU, 1 GB RAM, 5 GB SSD storage and 10 GB/month of outbound data transfer.
No card required
For: Developers
Read this first: the free tier exists only in some regions (EU1 / USE1 / USW1 — other regions get a 1-month free trial instead), and Cloady's docs warn that if a free workspace exceeds any resource limit, the whole workspace is billed. Treat the limits as hard walls.
