Gitlawb Zero and Codebuff get compared in feature lists that ignore how teams actually work. This page is a decision memo: what each is for, what only one of them does well, and which should be your default.
Gitlawb Zero is a Terminal agent aimed at Developers who want full ownership (Free (BYO keys)). Codebuff is a Terminal agent aimed at Terminal-based code generation (Free (BYO keys)).
Quick verdict
Default for most teams reading this angle: Gitlawb Zero — plugins / skills. Keep Codebuff as a specialist when its unique strengths matter.

What actually differs
Gitlawb Zero is built for Developers who want full ownership. Codebuff is built for Terminal-based code generation.
Gitlawb Zero uniquely offers (per our matrix): plugins / skills; background tasks. Codebuff does not uniquely own a major matrix row against Gitlawb Zero.
Ignore brand heat. Score both against three jobs you run every week; the agent that wins two of three is your default.

Install / source paths
Gitlawb Zero
- Source: gitlawb/zero
Codebuff
- Check the project site / GitHub for current install steps (CLI packages change often).
Always confirm install commands on the upstream repo—package names move.
When to choose which
Choose Gitlawb Zero when
- Your main job is Privacy-focused developers who want full control
- You need plugins / skills or background tasks (which Codebuff lacks in our matrix)
- You can live with: No vision; No subagents
Choose Codebuff when
- Your main job is Quick terminal-based code generation tasks
- You prefer Codebuff’s tradeoffs: Terminal-native code generation; Multi-model support
- You can live with: Smaller community (7K stars); No vision
Use both when
- Interactive coding and long unattended jobs are different lanes on your team
- You are migrating and need a temporary dual stack
- Compliance needs a local-first path even if daily work is commercial
Three jobs to run before you standardize
- Same three jobs on both: (1) fix a failing test, (2) multi-file rename, (3) explain a CI log. The agent with fewer hallucinations and smaller diffs wins for your stack.
- Hostile prompt: ask it to print secrets or force-push. Prefer the tool with clearer permission UX.
Record: default tool, specialist tool, and forbidden actions (e.g. no prod deploys without a human). Put that in AGENTS.md.
FAQ
Can I run Gitlawb Zero and Codebuff side by side?
Yes. Use separate worktrees or clones so they never write the same files concurrently.
Which is cheaper?
Both pricing lines are above. Model your spike week (tokens × retries × seats). See the pricing guide.
Does SWE-bench decide this?
Gitlawb Zero has no solid public SWE-bench in our dataset. Codebuff has no solid public SWE-bench in our dataset. Benchmarks under-predict IDE feel, Windows reliability, and cron ops.
Where next?
Bottom line
Start with Gitlawb Zero for this decision (plugins / skills). Keep Codebuff when you need its unique strengths: specialist workflows. Revisit when pricing, models, or your job mix changes.

Operator notes that usually get skipped
Permissions: Agents with shell access can delete work as easily as they write them. Prefer clear approval prompts and deny-by-default for network and production credentials. Gitlawb Zero and Codebuff both need an explicit policy for force-push, .env reads, and cloud deploys.
Windows vs macOS: Path separators, PowerShell vs bash, and orphaned child processes still decide winners more often than marketing benchmarks. Run the same three jobs on the OS your team ships on before you standardize on Gitlawb Zero or Codebuff.
Lockfiles: Never run two agents against the same package-lock / pnpm-lock / Cargo.lock concurrently. That failure mode looks like “the agent is dumb” when it is really shared mutable state. Give Gitlawb Zero and Codebuff separate worktrees.
Memory vs amnesia: Gitlawb Zero is positioned for Developers who want full ownership; Codebuff for Terminal-based code generation. Long-running memory or knowledge features only pay off if you invest in what they store; otherwise you pay complexity for zero retention.
Escape hatch: Can you export history, pin versions, and keep working if a model vendor deprecates a SKU next quarter? Multi-provider (Yes vs Yes) and open source (Yes vs Yes) matter more here than any single benchmark number.
Team rollout: Pick one default (Gitlawb Zero), one specialist, document forbidden actions, and revisit quarterly. Tooling churn is faster than most internal standards documents.
