Open-source building blocks for a modern TypeScript backend stack: HTTP, validation, SQL, storage and binary codecs.
CoderBuzz is a set of small TypeScript packages for building backends, each usable on its own or together. They are MIT licensed, keep dependencies to a minimum, and most run on Bun, Node.js and Deno, and the velox HTTP framework also runs on Cloudflare Workers. Performance numbers come from a public benchmark suite that anyone can rerun.
Published on npm under @coderbuzz. Benchmark figures are from the benchmarks repo (2026-10-11, Bun 1.4.3, 4-core Xeon).
HTTP framework for Bun, Node.js, Deno and Cloudflare Workers, with full type inference, built-in WebSocket pub/sub and 16+ middleware (JWT, CORS, sessions, CSRF).
Simple GET: ~125K req/s, level with Elysia and 2.6× Hono. Validated POST: 1.39× Elysia.
npm i @coderbuzz/velox
Schema validation with full type inference, built-in coercion, sync and async APIs, and schema metadata used by proto. About 9.5 KB min+gzip, no dependencies.
npm i @coderbuzz/veta
Type-safe SQL toolkit, not an ORM. One schema across SQLite, PostgreSQL, MySQL, MSSQL and ClickHouse, with migrations, batch inserts and streaming.
Query compilation 1.8–5.1× faster than Kysely.
npm i @coderbuzz/sql
Embeddable key-value store for Bun on SQLite or PostgreSQL: atomic commits with versionstamps, TTL, watch, and a durable queue. Pair with kvs-server and kvs-client for network access.
bun add @coderbuzz/kvs
MessagePack encoder and decoder that is safe on untrusted input, byte-compatible with @msgpack/msgpack, and has no dependencies.
Encode 3.5×, decode 1.6× vs @msgpack/msgpack.
npm i @coderbuzz/msgpack
Binary codecs compiled at runtime from veta schemas. No .proto files and no per-field tags, so the wire carries only the payload.
Benchmark payload: 65 B vs 111 B as MessagePack.
npm i @coderbuzz/proto
Compact binary framing for WebSocket messages, with a fault-tolerant client and a server handler for velox.
Messages 52–93% smaller than JSON.
npm i @coderbuzz/velox-ws-wire
Headless agent runner built from Z.ai's ZCode. An orchestrator sends a prompt over SSH or stdio and the agent works on the machine; zh tui opens the interactive interface.

Self-hosted platform for deploying Docker Compose stacks to your own VMs, with automatic HTTPS via Caddy, Cloudflare DNS and Git-push deploys. A single Go binary with SQLite.
Fast by design. Small bundles, few dependencies, and every speed claim measured in a public benchmark.
Correct. Strict types, tests and CI on every package.
Secure. Hardened parsing of untrusted input and a security policy in every package repository.
