OpenCode alternatives: who merges and releases?

If you are looking for OpenCode alternatives, the line to compare them against is where OpenCode itself stops: the pull request. OpenCode is an open-source coding agent from Anomaly (github.com/sst/opencode, MIT-licensed and, as of this writing, one of the most-starred coding agents on GitHub at over 216,000 stars). Its official GitHub integration does a lot on its own: run opencode github install, mention /opencode on an Issue, and it reads the Issue thread, creates a branch, implements the change, opens a pull request and reviews pull requests, all inside your own GitHub Actions runner.

What it does not do is merge or release. OpenCode's GitHub docs stop at submitting a PR, with no step that merges it or cuts a tag. Once a PR is open and reviewed, who decides it is safe to merge, and who owns the tagged release? That is where these tools differ.

I'm Lawrence Liu, the creator of Orbi. I checked each tool below, Orbi included, against its own documentation on 19 October 2026, and held them all to the same yardstick.

The yardstick

Four things decide whether an alternative fits: how you run it (terminal, editor, or an unattended runner), whether it opens the PR or leaves that to you, what happens after the PR, and the license and maintainer, since an open-source core is often why people are on OpenCode in the first place.

With any of these you still bring your own model keys and pay for inference, and what you pay depends on the model you pick, not on which agent wraps it. OpenCode already supports 75+ providers, including local models and DeepSeek, so if you want a cheaper model you can switch it inside OpenCode. So the thing worth comparing between these tools is the workflow.

The OpenCode alternatives, by what happens after the PR

Still ends at the pull request

These are the closest in shape to OpenCode: strong at turning a request into code, but the merge and release are yours to build.

• Claude Code runs as a terminal agent and in GitHub Actions, where it can turn an Issue into a pull request. Review is a separate thing: Anthropic's hosted Code Review comments inline on PRs, but its docs are explicit that "a review never approves or blocks the pull request, so the decision to merge stays with your team." Pick Claude Code when a reviewed PR is the handoff you want and you will run the merge and release yourself. Note that it is not open source (its license reserves rights), so it is not a like-for-like swap if the open-source license is why you are on OpenCode.
• Codex CLI brings OpenAI's Codex into the terminal, and codex exec puts the same agent into repeatable scripts and pipelines. Pick it when you are scripting the steps yourself and want a one-command agent inside them.
• Aider is terminal pair-programming with git in the loop: it maps the repo and commits its own changes, so ordinary git tooling can diff and revert them. It commits locally; opening the PR, and everything after it, is yours.
• Cline lives in your editor and terminal and asks for approval before it acts, though its Auto Approve settings let you waive that per action type, up to a full YOLO mode its own docs call dangerous. Pick it when you want to watch and approve each step by default, and loosen that deliberately.
• Goose (open source, Apache-2.0, now under the Agentic AI Foundation after starting at Block; aaif-goose/goose, over 55,000 stars) runs as a CLI and desktop app, with a headless goose run -t "…" or -i instructions.md that ends the session when the task is done, which makes it usable inside a CI step. It edits files and runs commands, but it does not open the PR for you, so the PR, the merge and the release are all your workflow.

For every tool in this group, the part after the pull request (deciding the PR is safe, merging it, cutting the release) is a pipeline you assemble out of GitHub branch protection, required checks and your own release steps. OpenCode's own GitHub integration already gets you to a reviewed PR, so switching to one of these agents does not change who owns the rest.

Carries the Issue past the merge

• Orbi takes an ai-ready GitHub Issue and runs a coding agent called Pi to write the change. A separate review session then reads that work, pinned to the exact commit it reviewed, and the runner merges only that reviewed commit. Publishing a release is the one step a person starts, by opening a release Issue; from there Orbi tags and publishes. Orbi is open source under AGPL-3.0, and you run it on your own keys. Orbi Cloud is the hosted version, which runs the same workflow for you and uses DeepSeek by default, so a run there does not touch your Claude subscription allowance.

Compared with the first group, Orbi automates the merge behind the review gate and leaves the release to one human action. The test guarantee stays whatever your repository's CI already enforces, since Orbi runs your existing checks.

Orbi publishes its measured cost. Orbi Cloud's cost page records 169 merged deliveries between 2026-09-16 and 2026-10-05, all on deepseek-flash (the default DeepSeek model), at a median of $0.082 per merged delivery and a 90th percentile of $0.22, both at off-peak DeepSeek rates. Those are Orbi's own deliveries on its own workflow, a different agent and task mix than your OpenCode runs, so treat them as a reference point for the hosted model rather than a prediction of your bill.

How to choose

To rank the OpenCode alternatives for your own setup, match each tool to how much of the line after the pull request you want to own:

• You want a different agent writing the code, and you are happy owning merge and release yourself: any of Claude Code, Codex CLI, Aider, Cline or Goose, chosen by whether you want a terminal, an editor, or a headless CI step.
• You are staying on OpenCode for its model flexibility and open-source license, and your real gap is the steps after the PR: keep OpenCode and build the merge-and-release pipeline on GitHub, or compare it against a runner that owns that line.
• You want the Issue carried past the merge to a tagged release without assembling that pipeline yourself: that is the boundary Orbi draws, with the human steps named above.
