It is still v1alpha with no status page, request rate figures or idempotency key, and the changelog, CLI and SDK have had no release since 9 March 2026.\n\n**OpenCode.** Runs with no key or account on free OpenCode Zen models. Most permissions default to allow, and SECURITY.md says the permission system is not a sandbox.\n\n## Before you call either\n\n### Jules\n\n1. Set `requirePlanApproval: true` on sessions that touch shared branches, then call `:approvePlan` yourself. API sessions otherwise run their plan without review\n2. Session creation has no request ID. After a timeout, list sessions and match the prompt or title before creating another\n3. Poll activities with a `create_time` filter and cache them. Activities never change once written\n4. Read the request fields from the discovery document at https://jules.googleapis.com/$discovery/rest?version=v1alpha. The field tables on jules.google render empty\n5. Budget against the daily task quota of 15, 100 or 300 by plan. New sessions are refused until the rolling 24 hours reset\n\n### OpenCode\n\n1. Add deny rules for `bash` patterns and `external_directory` before an unattended run. Most tools default to allow\n2. Set `\"autoupdate\": false` or `OPENCODE_DISABLE_AUTOUPDATE=1` and pin the version in CI\n3. Configure a provider key. With none, prompts go to free Zen models that may train on them\n4. Set `OPENCODE_SERVER_PASSWORD` before `opencode serve`. Without it the server runs unauthenticated\n5. Install `opencode-ai` for the 1.x server API and SDK. After `opencode upgrade --major`, use `@opencode/client` and add an `external_directory` ask rule\n\n## Questions\n\n### Which is better for AI agents, Jules or OpenCode?\n\nOpenCode scores 68.5 (B) on agent readiness against Jules's 44.5 (E), and leads in every scored category.\n\n### Are Jules and OpenCode open source?\n\nNo open-source release is listed for Jules.
