Customer support decision
Productlane
A focused replacement (ingest + retrieval + AI draft + Linear sync) is realistic for a small team using existing OSS components and LLM APIs, but reproducing the full hosted product (help center automation, multi-portal, SSO, polished UX and migrations) is a larger effort better left to the vendor.

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.
What a replacement has to do
- Ingest messages from channels, retrieve grounding documents, generate an AI reply draft, present draft for human review, and create/sync issue in Linear.
What it still won’t have
- Deep, out-of-the-box Linear integration and UI polish tying replies to issue status
- Hosted self-updating Help Center that auto-publishes from resolved issues
- Included AI credits / turnkey pricing and per-user billing
- Single-vendor uptime, security, and white-glove migration support
- Built-in multi-portal, multi-language, SSO, and SLA features
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal self-hosted customer support inbox and AI drafting assistant using Next.js (frontend), FastAPI (backend), Postgres (threads/threads metadata), Redis (job queue), Pinecone (vector search), and OpenAI-compatible LLM API. In scope: channel connectors for email and Slack (webhooks/IMAP), ingestion pipeline that normalizes threads into Postgres, document ingestion and embedding pipeline into Pinecone, an API endpoint that retrieves context and calls the LLM to generate a grounded reply draft, a simple web UI to review/edit/send drafts and record actions, and Linear integration to create/sync issues. Out of scope: multi-portal multi-language support, SLA management, enterprise SSO, polished changelog/portal pages, white-glove migration. Include retries, exponential backoff for external calls, input validation, basic auth for the UI, containerized deployment (Docker), automated tests for ingestion, retrieval, and reply-generation flows, and a README with run and deploy instructions.

- Evidence score67
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.
