Best Proxies for AI Agents 2026

There are two honest architectures, and the deciding variable is whether browser operations are your product or your plumbing.

Managed agent-browser platforms — Browserbase, Browserless, Steel, Hyperbrowser, Scrapeless — hand you a Chromium instance over CDP or a WebSocket URL. Your Playwright or Puppeteer code barely changes; your fleet disappears. What you are really buying is the surrounding identity and debugging layer: fingerprint management, CAPTCHA handling, session recording and replay, and persistence primitives such as Browserbase Contexts, which carry cookies, localStorage, IndexedDB and service workers between sessions but deliberately not the HTTP cache. Proxy bandwidth comes bundled and metered by the platform.

Your own browsers plus raw proxies means containers you schedule and IPs you buy per GB from a network like Oxylabs, SOAX or Novada. It is more code — warm pools, crash recovery, memory ceilings, fingerprint hardening — and materially cheaper per unit once you run continuously. Steel is the useful hedge: it is open source and self-hostable, so you can start managed and move in-house without a rewrite.

Start managed, instrument bandwidth per task from day one, and migrate only when the metered line item costs more than the engineer who would replace it.

Agent tasks are stateful. A research agent logs in, paginates, submits a form and returns three minutes later, every step tied to a session cookie the origin issued against one IP. Rotate the exit node mid-flow and the origin sees a session teleport between networks, a louder anomaly than any single request would have been. The rule: rotate per request for stateless fetches, hold one IP for the life of anything stateful.

That means one sticky identity per agent run. Oxylabs documents the clearest semantics of the group: a sessid value pins an exit node for ten minutes by default, sesstime extends it up to 1440 minutes, and sixty seconds of inactivity releases the IP regardless. Build to that reality — a sticky session is best effort, not a lease, so your agent must detect an identity change and retry the step rather than assume continuity.

Wiring is uniform because nearly everything descends from Playwright's proxy option — server, username, password, bypass — settable at launch or per context via browser.newContext(). browser-use exposes the identical shape as ProxySettings on the browser profile. Prefer per-context proxies so each concurrent agent gets its own IP inside one browser process, and key the session identifier to your task ID so a retry can deliberately reuse or deliberately burn an identity.

Browser time is cheap; bandwidth is not, and bundled bandwidth is where agent budgets get ambushed. Browserbase publishes proxy bandwidth at $12/GB on its $20 Developer plan and $10/GB on the $99 Startup plan, above 1GB and 5GB included respectively, with browser time at $0.12 and $0.10 per hour. Browserless meters everything in units — one unit is a block of up to thirty seconds of browser time — and charges 6 units per MB for residential traffic against 2 units per MB for datacenter, so your effective per-GB rate is a function of the unit price on your tier.

Now compare buying IPs directly: Oxylabs and SOAX list residential from $4/GB and Novada from $0.85/GB. The gap between bundled and raw bandwidth is the single largest driver of surprise agent bills, and a vision-model agent that screenshots every step can burn a gigabyte in an afternoon.

Three rules keep it sane. Block images, fonts and media unless the task genuinely needs pixels. Prefer markdown or text extraction endpoints over full page loads when you only need content. Attribute bandwidth per task so an expensive agent surfaces in a dashboard rather than an invoice. And if a platform accepts your own proxy credentials — Browserbase supports external proxies with domain-pattern routing — you can keep the managed browser while moving bandwidth onto a raw contract.

Pick the layer that matches your constraint. If browser operations are a distraction, take a managed agent-browser platform and pay the bandwidth premium until it hurts. If you are running agents continuously at volume, own the browsers and buy IPs per GB from a network with real session control. Either way, treat the proxy as the network-identity layer only, and budget separately for fingerprinting, pacing and challenge handling. Run agents the way you would want an agent run against you: honor robots.txt, rate-limit yourself well below what the origin can absorb, stay off logged-in and personal data, do not route around paywalls or platform terms, and choose providers with genuinely consent-sourced pools. Developer skepticism about how residential IPs are recruited is well earned — ask vendors how their peers opt in, and prefer the ones that answer in specifics.
