Automation and integrations decision
PUNKU GmbH
A minimal, single-tenant replacement (agent builder, connectors, runtime, memory, billing) is realistic for a capable developer using LangChain/Langflow building blocks; the vendor's compliance offerings and enterprise SLA are material but do not prevent a usable self-hosted alternative.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All PUNKU GmbH alternatives, with the arithmetic →
What a replacement has to do
- User defines an agent in plain English -> platform wires connectors and memory -> agent executes tasks (emails, calendar, integrations) -> store context and logs
What it still won’t have
- Enterprise SLAs, dedicated success manager, and guaranteed EU data residency
- Built, vetted catalogue of 2,700+ ready integrations and tested templates
- ISO 27001 attestation and turnkey on-prem options
What remains hard
- Compliance and regulation
ISO 27001 GDPR

Runnable build prompt
Build a self-hosted AI agent builder using Next.js + React for the UI, FastAPI for backend, Postgres for persistence, Redis for task queue, and LangChain (or similar) for agent orchestration. Core features in scope: (1) plain-English agent creation UI with template library, (2) connector framework for OAuth/webhooks for at least 20 common services, (3) runtime that executes LLM prompts and tool calls with pluggable model API adapter, (4) memory store and logs, (5) simple per-account credits meter and admin UI. Out of scope: enterprise SLA, ISO certification, and full catalogue of 2,700 integrations. Include error handling, authentication, unit tests for backend endpoints, and end-to-end tests for agent execution paths.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
