Best for
  • Small and mid-sized businesses that sell on WhatsApp and are willing to maintain their own VPS
  • Teams that need multi-tenant isolation and data sovereignty
  • Operators comfortable configuring Supabase, WAHA and an AI provider following the docs
  • Service businesses (clinics, real estate, e-commerce, infoproducts) that need audit, RBAC and LGPD features
  • Hevy PRO users who want AI assistants to directly access their workout data
  • People who prefer using MCP clients like Claude, Cursor, Codex for fitness tracking
  • Anyone needing summaries and insights from their training data
  • Scenarios needing clean, structured web context fed to an AI assistant
  • Users already on the Firecrawl platform who want to call its scraping capability directly via MCP
Not for
  • Non-technical users who expect a turnkey product without provisioning a server and a Supabase project
  • Scenarios requiring an official SLA or vendor-hosted support (the project is community-run and as-is)
  • Teams unwilling to configure third-party services (Supabase, AI provider, WAHA, Upstash, Resend and others)
  • Users who need fully automatic updates (updates are triggered by a click or by running the update script)
  • Users without a Hevy PRO subscription (API key required)
  • Users who want to use the server without an API key
  • Those needing delete workflows (Hevy API does not expose delete endpoints)
  • Simple static-page scraping where you don't want to depend on a third-party API and incur call costs
  • Sites that explicitly disallow automated access (robots.txt)
Required permissions
  • Root or equivalent access on a VPS (Docker, cron, ports 80/443)
  • Supabase project database and auth credentials (4 credentials plus the Session pooler connection string)
  • An API key from an AI provider (OpenRouter, Anthropic or OpenAI)
  • A WhatsApp number connected by QR code, or credentials for the official Meta Cloud API channel
  • Optional: Upstash Redis, Sentry DSN, Resend, and Nuvemshop integration credentials
  • Requires HEVY_API_KEY environment variable for Hevy API authentication
  • Can create, update, and replace workouts, routines, folders, templates, and body measurements via tools
  • Read operations can fetch workouts, routines, folders, templates, history, and user info
  • Requires a Firecrawl API key to call; cost and quota are governed by the Firecrawl account
  • firecrawl_agent/firecrawl_interact perform automated browser interaction, which may trigger login or form-submission flows on the target site
Risks and side effects
  • Self-hosting makes you the data controller for the instance, carrying LGPD compliance, backup and maintenance duties
  • If the cron (event-log-drain) is not installed and running, automations are created but never execute
  • Connecting WhatsApp through a non-official engine (WAHA) carries a risk of account ban, mitigated by throttling and jitter
  • The Supabase free plan does not back up automatically, so you must schedule backup.sh yourself
  • Updates only target published release tags; reverting to an older version requires the explicit --force flag
  • Optional Sentry telemetry sends error reports, with CPF, phone and email scrubbed, and can be turned off with SENTRY_DSN=off
  • API key can be misused if leaked; do not expose in URLs, logs, or screenshots
  • Create operations may produce duplicates on retry; update operations replace existing records
  • The server sends data to the Hevy API and may send telemetry to external services unless disabled
  • Bulk crawl/map tools can generate significant request volume against a target site — respect the site's rate limits and terms of service
  • firecrawl_agent's interactive action chain is longer — define task boundaries clearly before running it to avoid accidentally triggering actions on a sensitive site
