# Coding agent adoption, September 2026

> OpenCode was used by 53.6% of organizations running a coding agent through Requesty in September 2026, ahead of Claude Code at 23.3%.

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

## Key findings

1. OpenCode leads on reach: 53.6% of agent organizations used it.
2. OpenCode carries the most agent traffic at 49.0% of coding-agent requests, and the top two agents carry 86.1%.
3. OpenCode moved the most since August 2026: share of agent organizations went from 46.7% to 53.6% (+6.9 pp).
4. 12 agents cleared the publication floors this month.

## Data

| Agent | Share of agent organizations | Share of agent requests | Organizations (band) |
| --- | --- | --- | --- |
| OpenCode | 53.56% | 49.05% | 500+ |
| Claude Code | 23.28% | 37.06% | 100-499 |
| Kilo Code | 6.76% | 2.57% | 100-499 |
| GitHub Copilot | 6.64% | 5.21% | 100-499 |
| Qwen Code | 5.42% | 0.22% | 25-99 |
| Zoo Code | 3.60% | 1.17% | 25-99 |
| Pi | 3.41% | 3.15% | 25-99 |
| Cline | 3.35% | 0.20% | 25-99 |
| Roo Code | 2.07% | 0.21% | 25-99 |
| Zed | 2.07% | 0.53% | 25-99 |
| Claude Cowork | 1.34% | 0.02% | 5-24 |
| Cursor | 1.10% | 0.61% | 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.
