Codegen alternatives: how to keep turning Linear tickets into PRs
Codegen shut down after the ClickUp acquisition. Honest Codegen alternatives for the Linear ticket to PR workflow, plus a migration checklist.
Codegen was the first product built around a single loop: tag an agent in a Linear ticket, get a pull request back. The loop turned out to be right. The standalone company didn't make it. ClickUp acquired Codegen in December 2025, the standalone service stopped on January 9, 2026, and access ended for good on April 30. If your team wired its backlog into @codegen, you're now shopping for Codegen alternatives, and you have more credible options than existed when Codegen launched.
Product details checked August 2026. Vendors change; check their docs for current specifics.
What Codegen's Linear integration did
Codegen set the template most of the category now follows. You tagged @codegen in a ticket and it took the work from there: it moved the issue from Todo to In Progress to Done as it went, wrote the change in its own environment, and opened a GitHub PR linked back to the Linear issue. When it noticed something adjacent to the ticket (a bug, a missing dependency), it filed a follow-up issue instead of growing the PR.
That loop (ticket in, linked PR out, statuses handled for you) is the thing you're replacing. Judge any alternative by how much of it survives the move.
What the shutdown means
Three dates matter. ClickUp announced the acquisition in December 2025. The standalone service was discontinued on January 9, 2026, so no runs have happened since then. And the wind-down window Codegen gave its users closed on April 30, 2026.
The technology didn't die; it moved. Codegen's agents are becoming the foundation of ClickUp's AI coding features, and the farewell post offers users complimentary ClickUp access. If you were already leaning toward ClickUp as a tracker, that's a legitimate path. If your team runs on Linear, though, changing project trackers to keep a coding agent is backwards. Keep Linear. Swap the agent.
Codegen alternatives with a real Linear integration
Every tool below has a native Linear integration today, and each claim links to the page where we verified it. One disclosure: Sinatra is our product, so weigh that entry accordingly.
| Tool | Trigger in Linear | Where it runs | Pricing model |
|---|---|---|---|
| Sinatra | Assign the issue or mention @sinatra | Isolated per-task sandbox, shut down after the run | $20/member/mo; free tier is 5 tasks/day on your own key; no token markup |
| Tembo | Assign the issue to Tembo | Tembo's cloud sandbox | Credit plans from $20/mo |
| GitHub Copilot coding agent | Assign to GitHub Copilot or mention @GitHub | Ephemeral GitHub Actions environment | Copilot paid plans; one premium request per session plus Actions minutes |
| Devin | Assign, mention @devin, or add the devin label | Devin's cloud workspace | Free tier; Pro $20/mo, Max $200/mo, Teams $80/mo + $40/seat |
Sinatra is the closest match for the workflow Codegen users are losing. You assign the issue to Sinatra like a teammate or mention @sinatra in a comment; it posts progress into the issue while it works and opens a PR linked to the ticket. If the ticket is vague, it writes up requirements and posts them for approval before any code exists, and if you leave a PR review comment it pushes a revision to the same branch. It's BYOK: bring an Anthropic or OpenRouter key, or connect a ChatGPT subscription you already pay for, with no markup on tokens. The paid tier is $20 per member per month. The full loop is written up in Turning Linear tickets into GitHub PRs, and the workflow has its own page.
Tembo also takes an assigned Linear issue to a linked PR, with a different bet: you choose which underlying agent does the work (Claude Code, Cursor, Codex, and others), and Tembo runs it in its cloud and syncs status back to the issue. Pricing is credit-based, starting at $20/mo.
GitHub Copilot's coding agent (GitHub's changelog now calls it Copilot cloud agent) went generally available for Linear in July 2026. You assign an issue to GitHub Copilot or mention @GitHub, and it opens a draft PR from an ephemeral GitHub Actions environment, streaming progress into the issue timeline. If your org already pays for Copilot this is the shortest path: a session costs one premium request plus the Actions minutes it uses.
Devin connects to Linear as well: assign the issue, mention @devin, or add the devin label, and it scopes the work and links its session and any PRs back to the issue. Cognition sells mostly to larger engineering orgs; pricing runs from a free tier through Pro at $20/mo and Max at $200/mo, with Teams at $80/mo plus $40 per seat.
A short migration checklist
- Disconnect the Codegen app. Remove it from your Linear workspace's integration settings and uninstall the GitHub app, so a dead integration isn't holding webhooks or repository access.
- Settle anything still open with Codegen. The wind-down window closed April 30, 2026; support@codegen.com is the channel for billing questions and anything you didn't get out in time.
- Pick one replacement and scope it to a repo or two, not your whole org.
- Re-run real tickets. Take a handful of issues Codegen handled recently and hand the same ones to the new agent. Same input, comparable output; it's the cheapest honest evaluation you'll get.
- Update the habits. Issue templates, onboarding docs, and muscle memory all say "tag @codegen" somewhere. Find those spots and fix them.
Common questions
Is Codegen still running?
No. The standalone service stopped taking work on January 9, 2026, and the wind-down window closed on April 30, 2026. The team and technology now build ClickUp's AI coding features.
Do I have to move to ClickUp?
No. The complimentary ClickUp access in Codegen's farewell post is an offer, not an obligation. If Linear is your tracker, every tool in the table above plugs into it directly.
Which alternative is closest to Codegen's workflow?
Sinatra and Tembo mirror the shape most directly: assign a Linear issue, get a linked PR back. Copilot's coding agent costs almost nothing to try if your org already pays for Copilot, and Devin fits teams that want a heavier enterprise product around the agent.
What happens to my Codegen data?
Codegen's wind-down window for getting data out closed on April 30, 2026, and there's no documented export path since. If you still need something, support@codegen.com is the remaining channel.
If what you liked about Codegen was assigning a ticket and reviewing a PR a few minutes later, that loop still exists. Connect a repo and try it on the next small ticket in your backlog: start for free, or read the docs to see the setup first.
