## What to watch for

- **OpenCode**: The web UI's server-URL-override feature and local HTTP server have a real, disclosed 2026 security history (two now-patched advisories), so running it on a shared or untrusted network needs care.
- **Cline**: No built-in model. Cline is useless without an API key, a ClinePass subscription, or a local model, and results depend entirely on the model you bring.
- **OpenHands**: Individual Cloud plan is capped at 1 user and a maximum of 10 daily conversations.
- **Letta**: Smaller ecosystem and community than LangChain, LlamaIndex or Microsoft AutoGen.
- **goose**: Details here come from the vendor's own documentation site (goose-docs.ai) with one supporting GitHub issue in the project's own repository; independent third-party reviews of Goose are not available yet.

Best match first.

## Shortlist

### 1. OpenCode

Open source AI coding agent for the terminal, desktop, IDE and browser, with any LLM provider.

**Where it improves on Orbi:**
- [Reviews code: yes — Reviews diffs others wrote: a documented workflow runs it on pull_request events, and PR review comments hand it the file path, line numbers and diff context.](https://opencode.ai/docs/github/)
- [Multi-agent: yes — Primary agents invoke subagents that open child sessions, and several agents can be run in parallel on one project from separate sessions.](https://opencode.ai/docs/agents/)
- [Agent permissions: yes — Each tool resolves to allow, ask or deny, with glob rules per shell command or file path and per-agent overrides; defaults are permissive apart from external directories.](https://opencode.ai/docs/permissions/)

**Trade-offs against Orbi:**
- None found.

### 2. Cline

Open-source coding agent for VS Code, JetBrains, the terminal and CI, running on whichever model you bring.

**Where it improves on Orbi:**
- [Writes tests: yes — Test authoring is a named use case, covering unit and integration tests for existing large codebases rather than only tests for code it just wrote.](https://cline.bot/enterprise)
- [Reviews code: yes — It reviews diffs someone else wrote, either interactively on files and pull requests or unattended in GitHub Actions posting a review comment.](https://cline.bot/faq)
- [Whole-codebase work: yes — Repository-wide migrations are a stated use case, though the vendor is explicit that it never indexes a repo and instead uses partial-file analysis and summarisation.](https://cline.bot/)

**Trade-offs against Orbi:**
- [Pooled budget: partial — Organisation members draw on providers and billing configured centrally by an admin, and spend is reported per team and per member, but no per-seat budget cap is documented.](https://docs.cline.bot/enterprise-solutions/configuration/remote-configuration/overview)

### 3. OpenHands

Open-source software engineering agent with GUI, CLI, SDK and an enterprise control plane.

**Where it improves on Orbi:**
- [Writes tests: yes — Test generation and coverage maintenance is named as a supported workflow, not only code authoring, on the services page.](https://www.openhands.dev/services)
- [Reviews code: yes — A dedicated PR review workflow reads someone else's diff and posts inline comments on the pull request within minutes.](https://docs.openhands.dev/openhands/usage/use-cases/code-review.md)
- [Done-for-you service: partial — Software you run yourself, but the vendor also sells advisory and implementation engagements that deploy agents alongside your team.](https://www.openhands.dev/services)

**Trade-offs against Orbi:**
- [Open source: partial — The core is MIT-licensed open source, but the Enterprise control plane is described only as source-available under a commercial licence.](https://www.openhands.dev/pricing)

### 4. Kilo Code

Open source AI coding agent for VS Code, JetBrains, CLI and cloud, with 500+ models at provider rates.

**Where it improves on Orbi:**
- [Writes tests: yes — Test writing is named as part of the SDLC coverage Kilo sells to enterprises.](https://kilo.ai/enterprise)
- [Reviews code: yes — Kilo Code Reviewer analyses pull requests and comments in the PR.](https://kilo.ai/code-reviewer)
- [Whole-codebase work: yes — Indexes the repository and runs multi-step repo-wide work such as migrations.](https://kilo.ai/)

**Trade-offs against Orbi:**
- [Self-hosted: partial — The MIT clients can be forked and self-hosted and inference can be fully local, but Gateway, Cloud Agents and team administration are Kilo-hosted.](https://kilo.ai/)
- [Admin controls: partial — Teams gets data-privacy controls on models and providers; allowlists, RBAC and policy enforcement are Enterprise.](https://kilo.ai/enterprise)

### 5. Letta

Stateful agent harness, cloud and SDK for agents with persistent, git-versioned memory.

**Where it improves on Orbi:**
- [Reviews code: yes — Reviews diffs on demand or on every PR via the GitHub action's prompt input.](https://docs.letta.com/platform/github-action/index.md)
- [Multi-agent: yes — Seven built-in subagent types plus deploying any existing stateful agent as a subagent, in parallel or background.](https://docs.letta.com/configuration/subagents/index.md)
- [Agent permissions: yes — Four modes from strict to unrestricted, plus allow/deny tool patterns and a cross-agent memory guard.](https://docs.letta.com/configuration/permissions/index.md)

**Trade-offs against Orbi:**
- [Pooled budget: no — Quota attaches to each purchased Pro seat; unpaid seats get no Letta-hosted inference at all.](https://docs.letta.com/teams/quickstart/index.md)
- [Admin controls: partial — Org roles gate who reaches an agent; what the agent may run is set per machine or project, not centrally by an admin.](https://docs.letta.com/teams/permissions/index.md)
- [Audit log: no — No administrative audit log is published; the Enterprise list stops at RBAC, SSO, quotas and dedicated support.](https://docs.letta.com/pricing/index.md)

### 6. goose

Open-source local AI agent — desktop app, CLI and ACP server — running on the LLM provider you bring.

**Where it improves on Orbi:**
- [Reviews code: yes — A first-class goose review command reviews the working tree or a branch range, discovers repo-defined checks under .agents/checks, and runs them as parallel subagents with a severity filter.](https://goose-docs.ai/docs/guides/goose-cli-commands)
- [Multi-agent: yes — goose spawns subagents that run sequentially or in parallel with their own process isolation, driven either by direct prompts or by reusable recipe files, and can also wrap external agents such as Codex.](https://goose-docs.ai/docs/guides/context-engineering/subagents)
- [Agent permissions: yes — Four permission modes span full autonomy to chat-only, with per-tool Always allow / Ask before / Never allow rules, switchable mid-session; the default grants shell and file writes without asking.](https://goose-docs.ai/docs/mcp/developer-mcp)

**Trade-offs against Orbi:**
- [How it meters: partial — goose itself charges nothing, so the running cost is entirely your LLM provider's metered token or credit spend; no calculator or cost estimate is published and the vendor only tells you to keep provider credits topped up.](https://goose-docs.ai/docs/getting-started/installation)
- [Single sign-on: no — goose has no vendor accounts to federate, and the only authentication it documents for its own server is a shared X-Secret-Key value, with no SAML or OIDC option described anywhere in the docs.](https://goose-docs.ai/docs/gdk/acp/)
