CRM and sales decision
Streak
A small team can build a useful, narrow Gmail-integrated CRM (pipelines, email logging, mail-merge, AI summaries), but reproducing Streak’s full polished UX, broad integrations, enterprise controls, mobile apps, and scale requires significantly more product and operational work.

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
- Turn Gmail threads into pipeline records, sync emails to those records, run simple mail-merge/outreach, and surface AI-generated deal summaries.
What it still won’t have
- Deep, polished Gmail-embedded UX and mobile apps
- Enterprise features: custom roles, data validation, archived user handling
- Native marketplace integrations (LinkedIn, dialers) and Zapier breadth
- AI credits pooling and built-in credit purchasing/billing
- Large-scale reliability, priority support, and security/compliance guarantees
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal Gmail-native CRM using a Chrome extension + Node.js + Postgres. In scope: a Chrome extension that injects a pipeline/deal sidebar into Gmail, OAuth2 to read/send and label threads, backend REST API (Node/Express) with Postgres schema for pipelines/boxes/stages/contacts, mail-merge endpoint that personalizes templates and sends via Gmail API, and AI integration (OpenAI) to generate deal summaries and autofill a few fields. Include user auth (Google OAuth), a single-user/team mode (shared contacts), basic permission checks, error handling, logging, and unit tests for backend endpoints. Out of scope: mobile apps, enterprise RBAC, billing/credits UI, and 3rd-party connector marketplace. Deliver Dockerfiles for backend and Postgres, deployment scripts for a small VPS, and an install/run README.

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.
