OpenCode vs Gitlawb Zero: provider-neutral terminal use or developers who want full ownership?

OpenCode and Gitlawb Zero 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.

OpenCode is a Terminal agent aimed at Provider-neutral terminal use (Free (BYO keys)). Gitlawb Zero is a Terminal agent aimed at Developers who want full ownership (Free (BYO keys)).

Quick verdict

Default for most teams reading this angle: OpenCode — higher published SWE-bench (88.0%). Keep Gitlawb Zero as a specialist when its unique strengths matter.

Feature matrix

What actually differs

OpenCode is built for Provider-neutral terminal use. Gitlawb Zero is built for Developers who want full ownership.

OpenCode does not uniquely own a major matrix row against Gitlawb Zero. Gitlawb Zero does not uniquely own a major matrix row against OpenCode.

Ignore brand heat. Score both against three jobs you run every week; the agent that wins two of three is your default.

Strengths (from product positioning)

OpenCode

Pros: Multi-provider support; Free and open source; Skill-driven execution; Copilot provider integration.

Cons: Archived / no active development; No vision support; No subagents.

Gitlawb Zero

Pros: Full ownership, no vendor lock-in; Customizable keyboard shortcuts; Android Termux support; Atomic binary updates.

Cons: No vision; No subagents; Smaller community.

Install / source paths

OpenCode

• Package: @opencode-ai/sdk (npm) — try npx -y @opencode-ai/sdk or install per upstream docs
• Source: opencode-ai/opencode

Gitlawb Zero

• Source: gitlawb/zero

Always confirm install commands on the upstream repo—package names move.

When to choose which

Choose OpenCode when

• Your main job is Open-source alternative with flexible provider choice
• You prefer OpenCode’s tradeoffs: Multi-provider support; Free and open source
• You can live with: Archived / no active development; No vision support

Choose Gitlawb Zero when

• Your main job is Privacy-focused developers who want full control
• You prefer Gitlawb Zero’s tradeoffs: Full ownership, no vendor lock-in; Customizable keyboard shortcuts
• You can live with: No vision; No subagents

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

1. 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.
2. 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 OpenCode and Gitlawb Zero 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?

OpenCode lists 88.0%. Gitlawb Zero has no solid public SWE-bench in our dataset. Benchmarks under-predict IDE feel, Windows reliability, and cron ops.

Bottom line

Start with OpenCode for this decision (higher published SWE-bench (88.0%)). Keep Gitlawb Zero when you need its unique strengths: specialist workflows. Revisit when pricing, models, or your job mix changes.

Comparing agents is half the work. aiFiesta can simplify multi-model access while you test workflows.

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. OpenCode and Gitlawb Zero 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 OpenCode or Gitlawb Zero.

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 OpenCode and Gitlawb Zero separate worktrees.

Memory vs amnesia: OpenCode is positioned for Provider-neutral terminal use; Gitlawb Zero for Developers who want full ownership. 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 (OpenCode), one specialist, document forbidden actions, and revisit quarterly. Tooling churn is faster than most internal standards documents.
