Codex42 takes products from a blank repo to live - mobile & web apps, AI content pipelines, payments and the infrastructure underneath, including Mortarbase, our own Supabase-alternative backend platform.
The people who design it are the people who ship it. No layers, no telephone game.
The right model for each job - with cost metering, fallbacks and human review built in.
Mortarbase & SkyMailr mean we don't wait on vendors - backend, auth and email are ours.
Proven patterns from our own live apps mean we move fast without cutting corners.
Every line below runs in our own live products today. We bring the same stack and patterns to your build.
Multi-provider AI in real products - provider abstraction, fallback routing, structured tool output, streaming.
Photo understanding, AI narration, word-level transcription, and semantic search via embeddings.
AI image generation, programmatic video assembly, captions and audio alignment at scale.
Cross-platform iOS & Android - audio, camera, push, CarPlay / Android Auto, OTA updates.
Robust REST APIs, OpenAPI docs, clean service layers and data modeling built to scale.
Background processing for heavy AI work - retries, idempotency, stale-job recovery.
Live multiplayer over WebSockets - contests, matchmaking, leagues, leaderboards.
Our Supabase alternative - multi-tenant Postgres, auto APIs, auth, storage, realtime, RLS by default.
Transactional, lifecycle & marketing email - templating, A/B, workflows, tracking, deliverability.
Subscriptions, IAP, tiered gating, usage credits, referrals and affiliate payouts.
Schedule & auto-publish video to social platforms with OAuth linking and metrics.
Containerized delivery to Railway, programmatic provisioning, object storage, secrets, CI gates.
Zero-knowledge architectures, client-side encryption, key wrapping and sharing, row-level security, signed artifacts.
Beyond the browser: cross-platform desktop apps, Chrome extensions and command-line tools that slot into CI.
Our own container fleet streaming real Android devices into the browser, with an API and embed SDK for previews and automated QA.
Tool-using agents that read and write code, drive a real browser and operate a desktop - with concurrent sessions and per-session permission modes.
Safety enforced in code, not by the model: policy gates on every action, sensitive-field detection, fail-closed defaults, audit logs and human handoff.
Editors, terminals, workspace search and local-first developer environments - the tools engineers live in all day.
Three production engines manufacture, package and distribute media at scale - each a reusable capability we can build into your product.

Beta · TestFlightAudio-first micro-learning app: 10-15 min lessons, solo quizzes, live Kahoot-style trivia, weekly leagues & a social layer - powered by our Studio / Shorts / Auto-Social engines.
LiveOur Supabase alternative. A multi-tenant control plane that provisions a Postgres DB, auto REST API, auth, storage, realtime & edge functions per project - RLS-by-default, orchestrated on Railway.
BetaHonest photo-AI calorie & weight tracker. Snap a meal → Claude Vision estimates calories & macros with confidence bands and clarifying questions instead of false precision.
LiveAI Kanban + planning. An LLM turns a guided brief into a structured business plan, then extracts it into sprint-ready Kanban tasks. Drag-and-drop boards, PDF ingestion.
BetaOur multi-tenant email backbone for every app we ship - templating with approval & A/B, Celery-queued delivery, provider abstraction, webhooks, tracking & workflows.
Early productionAI long-form content platform. Turns a brief into blog series, eBooks, courses & campaigns - outline → sections → full content, streamed live, exported to PDF. Stripe + affiliate payouts.
ConceptA cozy direct-to-consumer cookie brand. We designed the full identity and an iOS ordering app - warm UI system, menu & customisation, cart, checkout and rewards - ready to build.
Describe an app, get a real one on your phone. A prompt becomes a live mobile app with its own backend, auth, payments, OTA updates and native store builds - built by an AI agent loop with automated QA on real devices.
BetaA block-based markdown editor: free offline desktop app plus a paid web app with a Claude writing assistant and grammar checker. Exports clean Markdown, standalone HTML and PDF.
BetaA zero-knowledge password and developer-secrets manager. Everything is encrypted on your device - the server only ever stores ciphertext. Web vault, Chrome extension, desktop app and a CLI that injects secrets into CI.
BetaReal Android devices streamed into the browser. Upload an APK, get an embeddable live device you can tap and type in - no install, no simulator setup. Runs our own container fleet and powers the Builder preview.
PrototypeEvidence-traced programming for personal trainers. Every prescribed set, rep and calorie cites the published guideline behind it, with safety gates that block a program when screening flags or scope-of-practice limits demand a referral.
PrototypeA VS Code-style IDE that runs on your own machine with a Claude agent built in - editor, terminal, file tree and an embedded browser the agent can drive. Multiple agent sessions run side by side, each with its own permission mode.
PrototypeA local voice-and-text assistant that fills forms and runs tasks in a real browser it controls with actual mouse and keyboard. Hard safety limits are enforced in code: it never clicks submit or pay, never types a password or card number, and hands control back to you.
A focused, senior process - no hand-offs, no bloat. The people who design it are the people who ship it.
We pin down the product, users and the one loop that has to work. Scope & architecture in days, not weeks.
Bold UI plus a real backend - AI, payments, realtime - built on patterns already proven in our own apps.
The right model for each job, with cost metering, fallbacks and human-in-the-loop review baked in.
Deployed on Railway with CI, monitoring and async workers - then iterated on with you, live.
Whether you have a napkin sketch or a product that needs AI, there's a way in.
You have an idea; we return a live product - design, mobile/web, backend, payments and launch.
You have a product; we add the AI feature that matters - done right, metered and reliable.
You need it to scale; we bring the backend, BaaS, email and DevOps - on our own tooling.
Reused across every build, so projects move fast and stay maintainable.
