FLIN
The language that replaces 47 technologies
A compiled, full-stack programming language built from scratch in Rust. One syntax for frontend, backend, database, and tooling. 3,200+ tests. 180 embedded UI components. Zero npm dependencies.
Building FLIN
The Abstract Syntax Tree: FLIN's Internal Representation
FLIN's Abstract Syntax Tree: how the compiler represents code as expressions, statements, views, and entities.
Hindley-Milner Type Inference in a Custom Language
How FLIN uses Hindley-Milner type inference to determine types without annotations -- implemented in Rust.
Code Generation: From AST to Bytecode
How FLIN's code generator transforms the AST into bytecode: opcodes, constant pool, and view instructions.
The Bytecode Format Explained
The FLIN bytecode format: instruction encoding, constant pool, view instructions, and the .flinc binary.
10 Sessions: From Zero to a Working Compiler
Building a programming language compiler in 10 sessions: lexer, parser, type checker, codegen, and VM in two days.
Error Diagnostics That Actually Help
How FLIN's error diagnostics help developers: source locations, colored output, and human-readable messages.
Five Design Principles That Shape Every Line of FLIN
The five design principles behind FLIN: simple, zero-config, reactive, intent-native, and memory-native.
The Golden Rule: One .flin File Is All You Need
FLIN's golden rule: one .flin file replaces 15 config files. No package.json, no tsconfig, no webpack.
Why We Chose Rust to Build a Programming Language
Why Juste A. GNIMAVO and Claude chose Rust to build the FLIN programming language compiler from Abidjan.
Writing Apps Like It's 1995 With the Power of 2026
FLIN brings back the simplicity of 1995 web development with the power of a 2026 compiler, VM, and database.
The Complete FLIN Opcode Reference
The complete FLIN opcode reference: arithmetic, control flow, entity, view, and closure instructions.
FLIN: The Language That Replaces 47 Technologies
One language for frontend, backend, database, and tooling. Built from scratch in Rust with 3,200+ tests. No npm. No Webpack. No framework fatigue.
