Self-hosted PaaS for deploying apps, databases, and services. Git-based deploys, Docker support, preview environments, and a clean UI.

Reactive backend - database, server functions, real-time sync, cron jobs, file storage. All TypeScript. This site's backend (courses, videos, user data) runs on Convex.

CDN, DNS, DDoS protection, and edge computing. Free tier handles most needs. This site uses Cloudflare for DNS and analytics. Workers for edge compute.

Drop-in auth for React/Next.js. Pre-built sign-in UI, session management, user profiles, org management. This site uses Clerk for authentication.

Open-source Firebase alternative built on Postgres. Auth, real-time subscriptions, storage, edge functions, and pgvector for AI embeddings. Generous free tier.

Serverless cloud for AI/ML workloads. Write Python with decorators, Modal handles GPU provisioning and scaling. Sub-second cold starts. Scales to zero. $30/mo free compute.

Run 50,000+ ML models with a simple API. No infrastructure management. Pay-per-second billing. Deploy custom models with Cog. Popular for image generation and audio.

Fastest inference for open-source models. 200+ models via unified API. Ranks #1 on speed benchmarks for DeepSeek, Qwen, Kimi, and Llama. Serverless pay-per-token pricing.

LPU-powered inference at about 500 to 1,000 tokens/sec on GPT OSS models. Purpose-built chip with on-chip SRAM instead of HBM. OpenAI-compatible API. Free tier available.

Wafer-scale AI inference at 3,000+ tokens/sec. The WSE-3 chip has 4 trillion transistors and 900K AI cores. 20x faster than GPU providers. OpenAI partnership for inference.

Durable workflows and background jobs for serverless. Step-level retries, scheduling, and event-driven functions.

Error monitoring and performance tracing with release tracking, session replay, and first-class Next.js support.

Modern browser automation from Microsoft. Auto-wait, role-based selectors, cross-browser, fast in CI.

Type-safe SQL builder and ORM for TypeScript. Zero runtime overhead, honest schema migrations, bring-your-own-DB.

Billing infrastructure for SaaS. Pricing tables, credit-based metering, checkout, and customer portal - all in TypeScript.

Self-healing browser automation harness that lets LLMs complete any browser task. 5,000+ stars in under a week.

Google's BaaS platform. Firestore (NoSQL), Realtime Database, Auth, Cloud Functions, Hosting, and ML. Free Spark tier; pay-as-you-go Blaze.

TypeScript ORM with a schema-first workflow. Prisma Client gives full type safety; Prisma Migrate handles migrations. Prisma ORM 8 covers Postgres, MongoDB, and SQLite; MySQL still needs Prisma ORM 7.

Serverless Postgres with branching. Free tier, instant database branches per PR, autoscaling compute, and scale-to-zero. Acquired by Databricks in 2025.

Database platform for MySQL on Vitess, PlanetScale Postgres, and Neki (sharded Postgres), with branching, non-blocking schema changes, and horizontal sharding. There is no free or hobby tier; PlanetScale Postgres single node starts at $5/month.

Run full-stack apps on lightweight VMs at the edge. Deploy via flyctl, scale across regions, attach Postgres and Redis. Pay-as-you-go pricing.

Heroku-style PaaS. Deploy web services, background workers, cron jobs, and managed Postgres from Git. Free tier for static sites and small services.

European cloud and dedicated server provider. Famously cheap dedicated boxes, generous bandwidth, and Cloud VPS that undercut AWS by an order of magnitude.

Amazon's core compute service. Hundreds of instance types, every region, deep integration with the rest of AWS. The default enterprise compute layer.

TypeScript-first schema validation. Define schemas once, get static types and runtime validation. The default validator for tRPC, Next.js server actions, and AI SDKs.

All-in-one JavaScript runtime, bundler, test runner, and package manager. Rewritten in Rust as of Bun 1.4 (August 2026), drop-in compatible with Node, dramatically faster install and start times.

The original server-side JavaScript runtime. V8 under the hood, npm ecosystem, and the default backend runtime for most production deployments.

Secure-by-default JavaScript and TypeScript runtime from Node's original creator, with built-in TypeScript, fmt, lint, and test. The Deno team joined Cloudflare in October 2026: the runtime gets one more year of bug-fix and security releases, and Deno Deploy shuts down six months after the announcement.

Fast Rust-based formatter and linter for JavaScript and TypeScript. One tool replaces Prettier and ESLint with sub-second runs on large repos.

The standard JavaScript and TypeScript linter. Massive plugin ecosystem, framework-specific configs, and integration with every editor.

Vercel's high-performance monorepo build system. Remote caching, task pipelines, and incremental builds. Drop into any pnpm or npm workspace.

Polyglot monorepo platform from Nrwl. Project graph, generators, executors, distributed task execution, and Nx Cloud for remote caching.

Utility-first CSS framework. Compose styles with class names, scan templates with the JIT engine, and ship tiny CSS bundles. v4 rewrote the engine in Rust.

Locally-scoped CSS for component-based apps. Plain CSS files with hashed class names, no runtime overhead, no learning curve.

Copy-paste React component collection built on Base UI (the default), Radix, or React Aria primitives and Tailwind. You own the source, customize freely, no library to upgrade.

Unstyled, accessible React primitives. Dialogs, popovers, dropdowns, and more, with full keyboard and screen-reader support out of the box.

Fast, disk-efficient package manager. Content-addressable global store, strict dependency resolution, first-class workspaces. Default for many TypeScript monorepos.
