# Coding agent adoption, June 2026

> OpenCode was used by 37.6% of organizations running a coding agent through Requesty in June 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: 37.6% of agent organizations used it.
2. Claude Code carries the most agent traffic at 44.4% of coding-agent requests, and the top two agents carry 82.0%.
3. Roo Code moved the most since May 2026: share of agent organizations went from 23.2% to 7.6% (-15.6 pp).
4. 12 agents cleared the publication floors this month.

## Data

| Agent | Share of agent organizations | Share of agent requests | Organizations (band) |
| --- | --- | --- | --- |
| OpenCode | 37.57% | 37.54% | 100-499 |
| Claude Code | 27.62% | 44.43% | 100-499 |
| Cline | 16.99% | 4.02% | 100-499 |
| Kilo Code | 8.70% | 5.24% | 25-99 |
| Roo Code | 7.60% | 2.22% | 25-99 |
| GitHub Copilot | 7.46% | 4.54% | 25-99 |
| Zoo Code | 5.25% | 1.39% | 25-99 |
| Zed | 2.21% | 0.44% | 5-24 |
| Cursor | 1.80% | 0.09% | 5-24 |
| Claude Cowork | 1.38% | 0.02% | 5-24 |
| Qwen Code | 1.24% | 0.07% | 5-24 |
| Codex | 0.69% | 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.
