Thrum lets coding agents message each other, so a coordinator and a reviewer can check work before it reaches you. It appeared on Show HN on 9 November 2026. The idea is that one agent working alone can miss mistakes, but a small team of agents, one coordinating, one reviewing, can catch problems early. Thrum gives agents in tools such as Claude Code, Codex and Cursor a way to talk to each other while they work.
Many developers now run several coding agents at once, sometimes in different tools, and keeping track of what each one is doing can be hard. Thrum sits between them. It passes messages, lets a reviewer agent look over a change before it is merged, and lets you approve or question work from a single inbox, on the web, by Telegram or by email.
Details below reflect the official site as checked on 10 November 2026.
What is Thrum?
Thrum turns a set of coding agents into a team. Instead of each agent working in isolation and reporting only to you, the agents can coordinate with each other. A coordinator agent can hand work to another agent, a reviewer agent can check the result, and a gate agent can verify a merge before it goes ahead. When an agent needs a decision, it can ask, and you can reply from the web inbox, from Telegram or by email, without opening the coding tool itself.
Key features
- Cross-tool agent messaging, so agents in Claude Code, Codex and Cursor can communicate.
- Reviewer and gate agents that verify work and check merges before they go ahead.
- A coordinator agent that organises work between the other agents.
- A web inbox for following agent work and replying to permission requests.
- Permission replies by Telegram and email, as well as on the web.
- Pro adds memory and a work queue, for longer-running agent teams.
Who is it for?
Thrum fits developers who run more than one coding agent and want those agents to check each other. It is useful for anyone who has felt the risk of letting a single agent merge code without a second look, and for teams that want a reviewer in the loop on every change. The free tier, which needs no account, makes it easy to try, and Pro adds memory and a work queue for longer-running agent teams.
Pricing
Thrum lists two plans on its official website. The Free tier costs $0 and needs no account. Pro costs $15.00 per month or $120.00 per year, with a 14-day free trial and no card required. Pricing may change; see the official website for current pricing.
