# Hashlogics

> We deploy working AI for working businesses. Hashlogics' senior engineers build AI agents, voice assistants, RAG systems, automation and custom software, ship them to a production standard inside the tools a business already runs, and keep them running. Clients in the US, UK, Switzerland and Australia.

- Positioning: We deploy working AI for working businesses — AI agents, automation and custom software built to a production standard and kept running after launch.
- Model: senior engineering pods paired with AI systems; clients own all code, models, data and IP. Every build starts with a fixed-fee Blueprint, credited in full against the build; builds are fixed-price per milestone.
- Segments: enterprises and startups.

## Tool reviews

> One tool we build on, reviewed from shipping with it. Not a feature list.

Index: https://www.hashlogics.com/stack

- [AWS review](https://www.hashlogics.com/stack/aws) — Worth the weight, once a system earns its own infrastructure.
- [Bubble](https://www.hashlogics.com/stack/bubble) — Real products ship on it. Watch the workload, not the drag and drop.
- [Celery review](https://www.hashlogics.com/stack/celery) — The right way to move slow work off the request path. Painful to run past a few workers.
- [Claude Agent SDK](https://www.hashlogics.com/stack/claude-agent-sdk) — The agent loop, already written. Permissions are the reason to use it.
- [Claude API](https://www.hashlogics.com/stack/claude-api) — Long context wins the build. Rate limits decide what ships after.
- [Claude Code review](https://www.hashlogics.com/stack/claude-code) — A year in production. Real gains, but a senior still watches the diff.
- [ClickUp review](https://www.hashlogics.com/stack/clickup) — Good enough to route tasks automatically. The API punishes hardcoded structure.
- [Deepgram review](https://www.hashlogics.com/stack/deepgram) — Fast enough for a live call. Endpointing is the setting that decides if it works.
- [Docker review](https://www.hashlogics.com/stack/docker) — Worth it once a team owns the containers, not before.
- [FastAPI review](https://www.hashlogics.com/stack/fastapi) — The right default for AI backends, if you size workers for real load.
- [Fireflies](https://www.hashlogics.com/stack/fireflies) — A solid transcript source for automation, once you verify the webhook yourself.
- [Google Calendar API review](https://www.hashlogics.com/stack/google-calendar-api) — Reliable for reading a calendar, punishing for keeping one in sync.
- [LangChain](https://www.hashlogics.com/stack/langchain) — Useful for the first month. Judge it on what you keep after.
- [LangGraph](https://www.hashlogics.com/stack/langgraph) — Agents that survive a restart. The state model is the product.
- [Make.com](https://www.hashlogics.com/stack/make-com) — Fast to build, and it discards failed runs unless you say otherwise.
- [MCP review](https://www.hashlogics.com/stack/mcp) — Solid enough to ship. Auth and versioning are still your job.
- [n8n](https://www.hashlogics.com/stack/n8n) — Good enough to run a client's operations on. Self-host it.
- [Next.js review](https://www.hashlogics.com/stack/nextjs) — We bet our own site on it. App Router still has sharp edges.
- [OpenAI API](https://www.hashlogics.com/stack/openai-api) — Easy to call, harder to run. Rate limits decide your architecture.
- [PostgreSQL review](https://www.hashlogics.com/stack/postgres) — Boring is a feature. Postgres is our default database until a workload proves it should not be.
- [React review](https://www.hashlogics.com/stack/react) — Our default frontend. Two builds since have used Vue instead.
- [React Native review](https://www.hashlogics.com/stack/react-native) — One codebase for two platforms. It cost us most on the hardware.
- [Redis review](https://www.hashlogics.com/stack/redis) — The right cache and queue backbone. A poor primary database.
- [SendGrid review](https://www.hashlogics.com/stack/sendgrid) — Our most-used email API. The failures show up months later, not on day one.
- [Socket.IO review](https://www.hashlogics.com/stack/socket-io) — Great until server two joins. Then the adapter decides everything.
- [Stripe](https://www.hashlogics.com/stack/stripe) — The default for taking money. Marketplaces are where it gets hard.
- [Supabase review](https://www.hashlogics.com/stack/supabase) — Worth betting a product on. Row-level security is where teams get hurt.
- [Twilio review](https://www.hashlogics.com/stack/twilio) — The default for voice and messaging, if you register early and verify every webhook.
- [Vercel](https://www.hashlogics.com/stack/vercel) — Deploys you stop thinking about. Know the limits before you hit them.
