GitHub lists six security advisories between January and July 2026, four rated High, and the default docs describe the 6.0 release candidate while 5.6.1 is the stable release.\n\n**Swell.** Live /:models schema with field types and descriptions for every store. One full-access secret key per environment, with no scoped or read-only key.\n\n## Before you call either\n\n### Spree Commerce\n\n1. Send a publishable key in `X-Spree-Api-Key` on every Store API call. Add `X-Spree-Token` with the cart token for guest carts, or a customer JWT as a Bearer token\n2. Send `Idempotency-Key` with the cart token or a customer JWT on cart, payment and completion calls. A request carrying only the publishable key is never cached\n3. Ask for `fields` and `expand` explicitly. Relations are left out by default and `limit` stops at 100\n4. Use a secret key with the narrowest scopes for the Admin API. `read_all` gives a read-only key, and the CLI's auto-minted local key is read-only\n5. Read the docs under `/docs/v5` for a 5.6 store. The default docs describe 6.0, which renames shipments to fulfilments and splits carts from orders\n\n### Swell\n\n1. Call GET /:models once and cache it. It's the ground truth for custom fields\n2. Check `result.errors` after every write. A failed validation still returns 200\n3. Use `$set` to replace an array. A plain PUT merges arrays by element id and never shrinks them\n4. Use an sk_test_ key while testing. A bare sk_ prefix is live\n5. Keep `expand` and `include` small. Each level past the first three points adds rate-limit weight\n\n## Questions\n\n### Which is better for AI agents, Spree Commerce or Swell?\n\nSpree Commerce scores 70.4 (BB) on agent readiness against Swell's 55 (C), and leads in 6 of 7 scored categories.\n\n### Do Spree Commerce and Swell need an API key?\n\nSpree Commerce takes an API key or an OAuth sign-in. Swell needs an API key.\n\n### Can an agent call Spree Commerce and Swell without installing anything?\n\nNo hosted endpoint is listed for Spree Commerce. Swell has a hosted endpoint at https://api.swell.store.\n\n### Are Spree Commerce and Swell open source?\n\nSpree Commerce is open source (BSD-3-Clause for the backend, MIT for the npm packages. Enterprise Edition code is under a separate commercial licence). No open-source release is listed for Swell.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/spree-commerce-vs-swell.json, and with the fewest tokens: https://www.anchorterminal.com/compare/spree-commerce-vs-swell.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"spree-commerce\", \"b\": \"swell\"}`.
