From GitHub's daily star counts.
Checked on GitHub.
Overview
Sellbird finds businesses matching your customer profile (OpenStreetMap or a paid source), reads their websites for buying signals, finds the decision maker and verifies one email address. It then drafts a short sequence, sends from Gmail, Microsoft 365 or SMTP, and drafts replies. Model calls go through the Claude Code CLI or Codex CLI on a subscription instead of an API key. Sends wait in an Outbox for approval unless autopilot is enabled.
Who it is for: Small teams and founders running their own cold email prospecting
Strengths
- Uses Claude Pro/Max or ChatGPT plan via CLI; no API key or per-token billing
- Default approval gate plus a no-model pre-send check for merge tags, links and bad addresses
- Can stop after verification and export a CSV for another sequencer
- Signal detection reads company sites with plain HTTP requests, no model calls
Weaknesses
- Needs your own mailbox and warmup; README recommends a separate sending domain
- Depends on a signed-in Claude Code or Codex CLI; subscription limits apply
- AGPL-3.0 since 0.4.0; earlier Harvey releases were MIT
- Docker is documented for Linux only; macOS needs Python 3.11+ installed
What it needs
- no GPU
- Docker + Compose
- Needs Claude Code CLI or Codex CLI, Gmail, Microsoft 365 or SMTP mailbox, Python 3.11+, SQLite database file
- Models: Claude (via Claude Code CLI), ChatGPT plans (via Codex CLI)
- port 5555
