Productboard

Build a closest honest personal substitute for Productboard in an empty repository. Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, and Resend; do not offer alternative stacks. The core loop is: collect manually imported feedback, merge duplicates, link evidence to features and a small roadmap, and publish a transparent status view. Make the first run work locally with one documented command. Store all user data locally by default and make export straightforward. Put secrets in .env, ship .env.example, and never commit credentials. Create public and private feedback intake with consent text and optional contact details. Support posts, votes, comments, tags, statuses, owners, and duplicate merging. Add a research note type with evidence links, quotes, themes, and confidence. Build search and filters across feedback, customers, segments, themes, and status. Provide email notifications, moderation, export, deletion, and an audit log. Publish a read-only roadmap or findings page using only explicitly public items. Include clear empty, loading, success, and recoverable error states. Add input validation, safe filenames, and graceful handling of unavailable APIs. Write focused tests for the core transformation and one end-to-end happy path. Create a README with setup, architecture, permissions, data location, and backup steps. Do not add accounts, billing, telemetry, analytics, or a hosted control plane. Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure. Deliberately leave out a paid research-participant marketplace. Deliberately leave out unlimited video storage and automated transcription. Deliberately leave out enterprise repositories, SSO, and governance. Finish by running the tests and listing the exact commands used.
