Stably Orca
by stablyai · stablyai/orca
Run multiple coding agents in parallel against the same repo, with merge orchestration — useful when one agent isn't enough.
Orca packages a multi-agent workflow as an IDE / harness. You can spawn parallel Claude sessions on a branch each, then orchestrate merging or selecting the best output.
Why use it
Key features
- Parallel agent sessions
- Branch-per-agent isolation
- Merge / select orchestration
- Built-in diff comparison
- Skill-style activation

Use Cases
Real-world ways to use Stably Orca
When to use: You're unsure which approach will work; want N agents to explore each.
Flow
-
Spawn
Launch N sessions with the same brief.✓ Copied
→ Branches per agent
-
Compare
→ Best approach identified
-
Merge
Take the best parts.✓ Copied
→ Final code
Outcome: Better selection at the cost of N× tokens.
Combinations
Pair with other MCPs for X10 leverage
Octopus picks plan; Orca executes in parallel

Cost & Limits
What this costs to run
- API quota
- N/A
- Tokens per call
- Multi-session cost
- Monetary
- Free OSS; LLM costs N×
- Tip
- Set cost caps — parallel sessions get expensive
Security
Permissions, secrets, blast radius
Minimum scopes: fs-read fs-write
Credential storage: Per-session branches
Data egress: None by itself
Troubleshooting
Common errors and fixes
Merge conflicts
Sessions should target disjoint paths when possible
