Bulut ajanları (cloud agents) vs Yerel terminal ajanları (local agents) Comparison

Code doesn't run on your machine — it runs in the vendor's isolated VM: parallel, event-driven, keeps going even after your laptop closes

VS
Yerel terminal ajanları (local agents)

Code never leaves — the agent runs in your own shell, right in front of you, with direct access to your internal network

Quick Verdict

There's no single right answer, but the decision tree is clear: if your work involves customer code, KVKK-scoped personal data, or access to an internal network/VPN, a local agent — or a cloud agent's self-hosted mode — is in practice the only safe path. Even Cursor itself keeps a self-hosted machines option for sensitive workloads; that's proof that the claim 'cloud is always secure' isn't absolute even coming from the vendor. For open-source projects, personal projects, and high-parallelism work like '10 independent PRs overnight,' the cloud agent wins — but that win usually comes at the price of a Pro+/Ultra-level subscription. 2026's real answer is a mix of both, not a prophecy — and it's visible in the product architecture of all three major vendors themselves: at Cursor's Projects launch on September 10, the coordinator runs in the cloud but "automatically triggers a local agent whenever something needs to be tested on your machine." Claude Code treats the same session as a first-class concept split by `cloud` and `local` tags. You should think about this duality when choosing the task, not when choosing the product: keep decisions and sensitive data local, and run volume and event-triggered repeat work in the cloud.

Pros & Cons

Bulut ajanları (cloud agents)

Pros

  • Can distribute parallel tasks across thousands of subagents in isolated virtual machines (Cursor Projects, Sep 10, 2026)
  • Runs event-driven and autonomous, triggered by a PR opening, a Slack message, or scheduled triggers
  • The session keeps running in the cloud even after your laptop closes
  • With the self-hosted machine option, code and secrets can stay inside the customer's own network (Cursor, Sep 2, 2026)
  • The environment is reproducible as a saved configuration (cloud environment)
  • Can now be launched without a GitHub connection (Aug 27, 2026)

Cons

  • High parallelism usually requires an upper subscription tier (Pro+/Ultra)
  • In standard (non-self-hosted) mode, code runs on the vendor's infrastructure — sensitive data needs extra sign-off
  • In ephemeral environments (GitHub Actions–backed), every run is set up from scratch, requiring a custom setup script
  • For non-GitHub integrations (Azure Boards, JIRA, Linear), only opening a PR is supported — no deep planning
  • Consumer/Pro tiers generally lack SSO/SCIM/audit log — enterprise compliance requires a separate package
  • Using a self-hosted machine brings a real machine-hour bill

Best For

Multi-PR tasks that run overnight on open-source and personal projectsTeam workflows that react automatically to PR/issue/Slack eventsLarge-scale refactor/migration waves that need high parallelismGreenfield projects without sensitive data that want fast iterationEnterprise teams with code-residency constraints, using self-hosted machines

Yerel terminal ajanları (local agents)

Pros

  • Works instantly with a one-line install (native install/Homebrew/apt/dnf/apk)
  • Code and secrets never leave your machine — no extra tunnel needed for internal network/VPN access
  • Near-zero latency, giving a synchronous 'pair programming' experience
  • Open-source options (like Aider) are completely free — no extra cost beyond the model API bill
  • The environment is entirely under your control — no third-party-specific environment configuration
  • Claude Code, Codex CLI, and Aider together have over 300,000 GitHub stars — a mature, actively maintained ecosystem

Cons

  • Parallelism tops out at your hardware's limit — no official ceiling for 'how many agents at once' has been published
  • Once the session ends (laptop closes, terminal exits), the work stops too
  • Event-driven automation like PR/Slack triggers isn't built in locally — you have to trigger it by hand
  • Environment reproducibility depends on your machine's current state — there's no saved 'cloud environment'
  • 24/7 autonomous/background operation requires extra infrastructure (cron, your own server)
  • Manual orchestration overhead grows for large-scale multi-repo migrations

Best For

Work involving customer code, KVKK-scoped personal data, or internal-network accessSynchronous, single-session pair-programming-style developmentLow-to-medium-volume daily workflows for open-source/individual developersEnterprise repos that must run in self-hosted/air-gapped environmentsFast trial-and-error debug sessions where network latency makes a difference

Frequently Asked Questions

It depends — yes, but not unconditionally. Even Cursor's own official position offers a self-hosted machines option instead of the standard cloud mode for sensitive code ('keep tool execution entirely in your own network') — meaning even the vendor doesn't claim it's 'always safe.' For open-source/personal projects, the standard cloud mode can be used safely; if there's customer code or sensitive data, self-hosted mode or a local agent should be preferred.
