Verifiable facts
The brief for this surface requires at least three facts that a reader can verify against a primary source. The list below is built from the bernstein adapter source and, when available, the upstream project's own pages.
- Bernstein ships a Atlassian Rovo Dev adapter at src/bernstein/adapters/rovo.py that wraps the upstream CLI as one of 42 routable agents. [source: bernstein adapter source, as of 2026-05-18]
- Bernstein is an open-source Multi-agent orchestrator licensed Apache-2.0, with a deterministic Python scheduler that routes work across CLI agents in parallel git worktrees. [source: bernstein repo, as of 2026-05-18]
- Bernstein writes an HMAC-SHA256 chained audit log under .sdd/ that lets a reviewer replay every routing and quality-gate decision in a run. [source: bernstein repo, as of 2026-05-18]
Where Atlassian Rovo Dev fits in Bernstein
Bernstein registers Atlassian Rovo Dev under the slug "rovo" and the registry name "rovo". The adapter source lives at src/bernstein/adapters/rovo.py in the bernstein repo and was last touched at build time 2026-05-18. The Atlassian Rovo Dev adapter file is 107 lines and 3,931 bytes long, fingerprinted 8a422f3d4cd7d7de (first 16 hex chars of SHA-256). No upstream GitHub repository is recorded in the bernstein adapter for Atlassian Rovo Dev; refer to the upstream vendor's documentation when auditing. The Atlassian Rovo Dev project's homepage at support.atlassian.com is the primary source for upstream release notes. The bernstein adapter file for Atlassian Rovo Dev does not yet carry a "Last verified against upstream" line; this means the adapter still tracks an unpinned upstream binary. Bernstein routes tasks to Atlassian Rovo Dev when its pass rate on similar work clears the configured threshold, otherwise the deterministic Python scheduler picks a different adapter from the 42-adapter catalog.

When to pick which
Choose Atlassian Rovo Dev
Reach for Atlassian Rovo Dev when the work is a single thread that fits one agent: in a single-process terminal session, designed for single-instance use per repo. Auth model is configured per upstream docs. You skip the orchestrator round-trip and get the smallest possible surface between you and the model.
Choose Bernstein
Wrap Atlassian Rovo Dev under Bernstein when the goal splits into parallel tasks, when you want an HMAC-chained audit log on every routing decision, or when a deterministic Python scheduler (no LLM picking who runs what) is a hard requirement.
FAQ
Does Bernstein replace Atlassian Rovo Dev?
No. Bernstein wraps Atlassian Rovo Dev as one of 42 CLI adapters and routes tasks to it based on per-task pass-rate history. Atlassian Rovo Dev keeps running unchanged; Bernstein decides when it gets work.
Can I run Atlassian Rovo Dev alongside other agents in the same repo?
Yes. Each agent runs in its own git worktree under .worktrees/, so file edits never collide. Bernstein merges results back to the trunk only after the configured quality gates (lint, types, tests) pass.
Is this comparison page handwritten?
No. The template is fixed; every fact and every link is pulled from the bernstein adapter source in the master branch and (when available) the upstream project's own pages. The data extractor lives at scripts/gen-compare-data.mjs. No LLM writes the prose.
