Key takeaways
- Tencent's June 5, 2026 announcement identifies CodeBuddy as the coding agent in a plugin, IDE, and CLI suite, distinct from WorkBuddy.
- The CLI can serve a local web UI on 127.0.0.1 with agent modes, workers, tasks, and remote control.
- Domestic list prices are published in RMB with time-boxed credit bonuses; international live cards were not verified in this review.
- Hunyuan Hy4's August 28 two-week free preview on CodeBuddy/WorkBuddy is expired and is not a permanent free SKU.
FAQ
What is Tencent CodeBuddy?
Tencent Cloud's coding assistant: IDE plugins, a standalone IDE, and a CLI that can also serve a local web UI. It is not WorkBuddy, Tencent's broader productivity agent.
Is CodeBuddy free?
China personal docs describe a free credit allowance plus paid Standard/Advanced/Flagship plans. Hy4's two-week free preview ended around mid-September 2026. Confirm the live catalog for your region.
How is CodeBuddy different from WorkBuddy?
Tencent's June 2026 suite announcement treats CodeBuddy as the coding agent and WorkBuddy as a separate productivity agent. Do not copy WorkBuddy enterprise promotions onto CodeBuddy list prices.
Does CodeBuddy include Hunyuan Hy4?
Tencent's August 28, 2026 preview announcement said Hy4 would be available on CodeBuddy and WorkBuddy for two weeks. That window is not ongoing free pricing.
Executive Summary
Tencent CodeBuddy is Tencent Cloud's coding agent, announced June 5, 2026 as part of a productivity-agent suite with plugin, IDE, and CLI interfaces. That announcement is the reason it belongs in a foundation-lab coding-agent discussion: Tencent develops Hunyuan models and ships a first-party coding client.[1]
Checked September 23, 2026. CLI docs describe local serving (codebuddy --serve on 127.0.0.1) with agent modes, workers, tasks, and remote control. This review did not obtain a live international pricing table from codebuddy.ai (the host was not reliably reachable from the research environment). China-catalog figures below are labeled as such. Hunyuan Hy4's two-week CodeBuddy/WorkBuddy preview, announced August 28, 2026, must not be written as evergreen free access.[2][3]
| Attribute | Current evidence |
|---|---|
| Provider | Tencent Cloud.[1] |
| Execution | Local plugin/IDE/CLI; CLI web UI binds to localhost.[2] |
| Interfaces | Editor plugins, IDE, CLI, local web UI.[1][2] |
| Entry tier | Regional catalogs; Hy4 preview was time-boxed.[3] |
| Category | Foundation Lab Coding Agents |
Product Overview
Keep three names separate:
- CodeBuddy — coding agent (this profile).
- WorkBuddy — Tencent productivity agent in the same June suite. Enterprise credit promotions for WorkBuddy are not CodeBuddy list prices.[1]
- Domestic vs international — codebuddy.cn / Tencent Cloud China versus codebuddy.ai. Do not copy RMB SKUs onto USD pages or the reverse.
A practical CLI evaluation is to install the documented binary, run codebuddy --serve, and complete a bounded repository edit through the local UI while watching which model account is billed. That procedure was not executed here.[2]
Technical Architecture
Public CLI web-UI docs establish local HTTP serving and agent/worker/task controls. They do not establish a hypervisor sandbox or a Tencent-hosted coding VM. Treat permission prompts and any bash sandbox mentioned in regional docs as product-specific until the live page for your build is re-read. Independent security audits were not found in this pass.
Pricing & Licensing
Hy4: Tencent's August 28 preview said Hunyuan Hy4 would be free on CodeBuddy and WorkBuddy for two weeks. That promotion is expired as of this review. Remaining Hy3 or other campaign dates, if still published, should be copied with their end dates rather than as base SKUs.[3]
International USD cards were not verified live. An older archive cited in secondary notes listed a discounted Pro around $10; that is not used as current price here.
China personal/enterprise RMB catalogs exist on Tencent Cloud documentation (free credit tier plus paid seats). Because those pages were not re-opened in this session's primary browser pass, this profile does not reprint specific RMB numbers. Open the regional pricing page at purchase.
Licensing is Tencent Cloud commercial terms, not an MIT/Apache client grant established here.
What Developers Say
Independent English-language first-hand reviews were thin in this search. Marketplace install counts are not quality evidence. No hands-on CodeBuddy run was performed.
Competitive Positioning
| Alternative | Why compare |
|---|---|
| Qwen Code | Another China-lab coding client with a documented open-source CLI. |
| Tembo | Multi-harness operation. No Tencent-documented CodeBuddy integration.[4] |
Disclosure: Ry Walker is Tembo's co-founder and CEO.
Assessment
Include CodeBuddy when comparing foundation-lab clients that Tencent actually ships. Verify region, SKU, and whether Hunyuan Hy4 is still a preview before quoting price or model access. Do not collapse it into WorkBuddy.
