404inc Capabilities

Eight disciplines.
One compounding platform.

Capabilities aren't a checklist. They're the moves we've been making for forty combined years across every layer of the stack — from edge-routed compute to event-sourced data, from observability primitives to AI-native orchestration.

Hover any cell.

Each capability is a discipline we ship at production grade — measured against scale, latency, and the half-life of every dependency it ships with.

/ 01
Platform Architecture

Event-sourced foundations. Domain logic outside the framework. Multi-tenant scaffolding from commit zero.

CQRS · DDD · HEXAGONAL
/ 02
Distributed Systems

Consensus, replication, idempotency. Built for partial failure as the default state, not the edge case.

RAFT · NATS · KAFKA · gRPC
/ 03
Edge Compute

Latency as a product feature. Workers, durable objects, and edge-resolved identity across 14+ regions.

CLOUDFLARE · FLY.IO · DENO
/ 04
Real-time Surfaces

Sub-50ms presence. Cryptographically signed feeds. Phoenix LiveView and CRDT-backed collaboration.

ELIXIR · CRDT · WEBSOCKET
/ 05
Data & Analytics

Postgres for transactions. ClickHouse for analytics that answer in sub-second. pgvector for embeddings.

PG · CLICKHOUSE · DUCKDB
/ 06
AI-Native Layer

Provider-agnostic model routing. Real-time eval. Embedded RAG over customer-grade vector storage.

ORCHESTRATION · RAG · EVAL
/ 07
Observability

OpenTelemetry from commit zero. Structured logs, traces, metrics. If we can't see it, we don't ship it.

OTEL · GRAFANA · TEMPO
/ 08
Migration & Rescue

Strangler-fig migrations. Legacy decomposition without downtime. The rewrite that doesn't make the news.

STRANGLER · DUAL-WRITE

A snapshot from active platforms.

Every metric below is something we measure, expose, and audit on a daily cadence. Numbers refresh live.

Anatomy of a 404inc platform.

Every system we ship follows the same architectural backbone. The framework rotates. The shape doesn't.

Bring us the impossible.

If your platform problem fits one of the eight disciplines above — or sits at the intersection of three — we should talk.
