# Coding agent adoption, May 2026

> OpenCode was used by 34.3% of organizations running a coding agent through Requesty in May 2026, ahead of Claude Code at 27.6%.

Question: Which coding agents do teams run through an LLM gateway?

## Key findings

1. OpenCode leads on reach: 34.3% of agent organizations used it.
2. OpenCode carries the most agent traffic at 57.1% of coding-agent requests, and the top two agents carry 84.5%.
3. 10 agents cleared the publication floors this month.

## Data

| Agent | Share of agent organizations | Share of agent requests | Organizations (band) |
| --- | --- | --- | --- |
| OpenCode | 34.25% | 57.08% | 100-499 |
| Claude Code | 27.59% | 27.40% | 100-499 |
| Roo Code | 23.22% | 8.89% | 100-499 |
| Cline | 20.23% | 3.07% | 25-99 |
| Kilo Code | 9.43% | 3.05% | 25-99 |
| Claude Cowork | 2.76% | 0.02% | 5-24 |
| Zed | 2.76% | 0.09% | 5-24 |
| Cursor | 2.07% | 0.31% | 5-24 |
| Codex | 1.38% | 0.01% | 5-24 |
| GitHub Copilot | 1.38% | 0.00% | 5-24 |

## Method

- Agents are detected from the User-Agent product token and the X-Title header of each request, using the same rules as the public coding-agents classifier. Requests that match no rule are not counted.
- An organization can use more than one agent, so organization shares add up to more than 100%.
- A row is published only when it has at least 20 requests, at least 5 distinct organizations, and no single organization above 80% of its traffic. These are the same floors /rankings uses. Rows below the floors are withheld, not estimated.
- Only shares, rates, medians and organization bands are published. Absolute request, token and spend totals stay private.

## Caveats

- Agents that connect to providers directly, such as Cursor and GitHub Copilot by default, only appear when users route them through Requesty. Their share here understates their market share.
- Agents that do not send a recognisable User-Agent or X-Title are not counted.
- Discontinued agents stay in the history; they drop out of a month when they fall below the floors.
