Install the tina4 CLI with one command, then run tina4 setup to scaffold your first project.
curl -fsSL https://tina4.com/install.sh | shLet a model that already knows Tina4 write the routes, models, and Tina4CSS. It runs on our infrastructure, so the boilerplate costs nothing and your paid tokens stay free for the real work.
Register Now ->v3.13.52 (2026-07-04) - full notes
Frond gains live blocks. Wrap a region in {% live %} and Frond paints it on the server, then refreshes it on its own over polling, Server-Sent Events, or a WebSocket you already own. The block renders real content on first paint, and its data provider re-runs with each request so an authenticated block re-checks auth every refresh. One frond.js client drives it, byte-identical across all four frameworks. This release also restores pgsql:// as a PostgreSQL connection scheme (the spelling PDO, Laravel, and Doctrine use), and the built-in SCSS compiler now evaluates rgba(#hex, a), rgb(), mix(), lighten(), and darken() instead of passing them through as invalid CSS.
Recent releases (v3.13.40 - v3.13.51) - the dev MCP server moved to the current Streamable HTTP transport over a single /__dev/mcp endpoint, with the legacy HTTP+SSE handshake kept for older clients; Swagger gained per-route security and reusable component schemas; queues were unified on one lifecycle across all four frameworks, with a reservation and visibility timeout so a dead consumer never strands a job; the test suite moved onto real services (no mocks) and caught a batch of live database, broker, and Firebird bugs; i18n was hardened with partial interpolation that never throws; the tina4-js runtime bundle was refreshed; and a Ruby fix made integer primary-key path parameters match on SQLite.
Highlights since v3.12.3 - the v3.13 line unified the cache backend (memory, file, redis, valkey, memcached, mongodb, database), gave queues a full lifecycle (priority pop, retry backoff, automatic dead-lettering), added a request-scoped query cache, shipped live dev tooling over WebSocket and a Streamable HTTP /__dev/mcp endpoint, hardened the ORM and database layer to fail loud, and ran a broad security pass. See the full release notes for every version.
Pick a language. Each book stands on its own: you can read Python cover-to-cover, then pick up the PHP book later and recognise every pattern.
node:http, file-based routing, ESM-only.stream_select server, zero composer deps in core.Every book has a printable PDF with a clickable table of contents. Every chapter stays in sync with the code: release notes, version numbers, and example output are regenerated with every point release.
Python, Node.js, PHP, and Ruby share the same project structure, CLI, template syntax, route patterns, and .env variables. Learn one, know all four.
The Rust-based `tina4` CLI detects the language, compiles SCSS, watches files, and delegates to the framework. `tina4 init`, `tina4 serve`, and `tina4 migrate` run the same across Python, PHP, Ruby, and Node.js.
Every Tina4 backend runs on the standard library. No native addons, no node-gyp, no vendor tree. Your requirements.txt / composer.json / Gemfile / package.json each hold one entry.
Drop a file in `src/routes/`. The framework registers it. Typed path params (`{id:int}`, `{slug:slug}`, `{id:uuid}`) reject bad input with 404 before your handler runs.
Real-time bidirectional comms and server-sent events across all backends. Redis backplane for horizontal scaling. The same `WebSocketServer` API in every language.
One Twig-compatible engine. Variables, loops, template inheritance with `{{ parent() }}`, macros, filters. Write your layout once, render it in any language.
SQLite, PostgreSQL, MySQL, MSSQL, Firebird, MongoDB. `Database::create("sqlite:///app.db")` works anywhere. `sqlite:///path` is relative to your project root, the same convention across all four frameworks.
GET routes are public, POST/PUT/PATCH/DELETE require a bearer token. JWT (HS256/RS256), PBKDF2 password hashing, rate limiting, CSRF form tokens, all built in, nothing to configure.
Add an `@description` decorator to your route. Visit `/swagger`. Your API docs appear, typed, grouped, ready for your team.
Zero-dependency GraphQL engine. Point it at your ORM models, get a full schema with queries, mutations, and a GraphiQL IDE. `POST /graphql` in one line.
File-backed by default, RabbitMQ/Kafka/MongoDB when you scale. Producer/consumer/dead-letter semantics consistent across languages. Periodic tasks via `background(fn, interval)`, no threads.
Routes, requests, SQL runner, queue monitor, mailbox, WebSocket inspector, error tracker, AI chat, a shared SPA across all four frameworks. `TINA4_DEBUG=true` turns it on.
