AI Gateway

One gateway to AI models. Your keys, European control.

An OpenAI-compatible endpoint for every project: Claude Opus, Sonnet and Haiku via Anthropic, GPT, Mistral or your own server — on your own keys (BYOK). Plus rate limits, budgets, caching, PII redaction (national ID, e-mail, phone), logs and automatic embeddings into pgvector.

Capabilities

What you get with AI Gateway

OpenAI-compatible

Change only the base URL and key in any SDK. SSE streaming, tools and images are translated to/from the Anthropic Messages API.

BYOK and encryption

Anthropic, OpenAI, Mistral or custom-endpoint keys are encrypted at rest and never written to logs.

Keys, limits and budgets

Gateway keys with scopes, per-minute rate limits and monthly budgets; notifications at 80% and 100%.

Cache and fallbacks

Exact-match response cache with TTL and automatic fallback to a backup model on provider errors.

PII redaction

Polish PESEL numbers (checksum-validated), e-mails and phone numbers are masked before the prompt leaves your project.

Vector pipeline

Pick a table and column — we generate the SQL: vector column, trigger, pgmq queue and an embedding worker.

Use cases

What teams use it for

Assistants and chatbots

Streaming answers, prompt templates and cost control per key.

RAG on your own data

Automatic embeddings of Postgres tables and semantic search without a separate database.

Sensitive data

PII redaction and logs without prompt bodies — for apps handling personal data.

The rest of the platform

Every service shares the same database, authentication and permissions.

Postgres databaseA dedicated Postgres 17 for every project: REST and GraphQL, table and SQL editors, backups with restore, reports and advisors.AuthenticationSign-up and sign-in, JWT sessions, MFA and Row Level Security — with user management in the dashboard. OAuth providers, magic links (once SMTP is configured), hooks and e-mail templates.StoragePublic and private buckets, signed URLs and RLS policies. Browse and upload files right from the dashboard.Edge FunctionsTypeScript/Deno functions deployed from the dashboard, API or MCP — with templates, secrets, an invocation tester, logs and metrics.WorkersHeavy, long-running jobs in Python, Node.js, Bun, Go or your own Dockerfile — HTTP, background, cron and queue consumers, each in an isolated gVisor container.SitesFrontend hosting next to your database: static sites (Vite, Astro, SvelteKit) and SSR apps (Next.js) with a preview for every PR, instant rollback and custom domains with TLS.RealtimeListen to database changes, broadcast and presence over WebSockets — in real time.Vectors & AIpgvector out of the box: embeddings, semantic search and RAG without a separate vector database.Transactional emailSend app email through an API: your own domain with DKIM, templates, event webhooks, a suppression list and a sandbox inbox for testing.MCP serverConnect Claude, Cursor and other AI agents to your database through the Model Context Protocol.
