Tool ·
Drop an executable or library — Mach-O (thin or universal), ELF or Windows PE — and see its load commands or headers, libraries and run paths, symbols demangled, fixups, the code signature with entitlements and requirements, a checksec-style hardening list, Go build info, Rust crates, strings, a hex view of any section and a size treemap.
Tool ·
Open a CPU, heap or lock profile — Go pprof, collapsed stacks from async-profiler, perf or cargo flamegraph, JDK Flight Recorder, a Node/Chrome .cpuprofile, speedscope or perf script — and read it as a flame graph or icicle with search, a top table, callers and callees, and a red/blue differential against a baseline, all in the browser.
Tool ·
Paste JSON samples (or a JSON Schema) and get TypeScript, Zod, Java records with Jackson (or Lombok classes), Kotlin, Go structs, Rust serde, Python pydantic or dataclasses, protobuf, or JSON Schema — merging samples to find optional fields, nulls, unions, enums, dates, UUIDs, maps and tagged unions.
Tool ·
Paste a Go struct, Rust struct or enum, C struct or Java class and see every byte — fields, padding, object headers, enum tags and niches — on 64-bit and 32-bit targets, with Go's fieldalignment reordering, rustc's own field order, HotSpot's field packing, and a gallery of runtime internals (slice and interface headers, Vec, Box, Rc, fat pointers, String, HashMap.Node).

The engine behind this site — a Rust static-site generator with a CLI, REST API, MCP server, and desktop app — is now on GitHub under the MIT licence.
Playground ·
Edit Rust and Go here; they are compiled and run by the official Rust and Go playgrounds, with the output shown in the page.

How I built AOEE, an in-memory relationship cache for social-graph queries: posting lists borrowed from search engines, four adaptive encodings, set maths instead of joins, and friend-of-friend suggestions with a budget.
Tool ·
Convert between JSON, YAML, CSV/TSV, XML, TOML, and query strings, and generate TypeScript, JSON Schema, Go, Rust, and Python types from JSON.
Tool ·
Write and run code in 29 languages — JavaScript, TypeScript, Python, Java, Kotlin, C, C++, Rust, Go, R, PHP, Perl, Ruby, Lua, OCaml, Fortran, Clojure, Scheme, Prolog, BQN, Forth, BASIC, SQLite, DuckDB, HTML, p5.js, GLSL, Brainfuck and Befunge — and share it as a link.
Project ·
The app that builds and publishes this site — a Rust core with a CLI, a REST API, an MCP server for AI assistants, and a desktop app.

What it takes to build a complete social network as one coherent app — feed ranking, social graph, search, messaging — with Spring Boot, React, PostgreSQL, OpenSearch, and a Rust graph cache.
Project ·
A full-featured social network — feeds, profiles, friends, groups, pages, messages, search, and an admin dashboard — built on Spring Boot, React, PostgreSQL, OpenSearch, and my Rust graph cache.
Project ·
A TAO-inspired in-memory relationship cache for social-graph queries, with compressed posting lists and fast set operations for friend-of-friend queries and feeds.
Project ·
A secrets-management server in Go with encrypted storage, path-based policies, versioned secrets, audit logging, leader-follower replication, and client libraries for Go, Java, Python, and Rust.
