C++ SDK

Two C++17 libraries cover the Solari products: solari::browser (target solari_browser) for browsers, and solari (target solari) for sandboxes. Both are blocking and synchronous. Every call is one round-trip over libcurl, with nlohmann/json for wire types. VMs (GUI desktops) are created with createDesktop(), but driving their GUI needs another SDK; see VMs.

Not published: consumed as source

Neither library ships to a registry. There is no Conan, vcpkg, or system package. You pull them into your build with CMake FetchContent, as below. This applies to every page in this section.

Take only the FetchContent_Declare you need. The two are independent. Fetched for you at configure time: nlohmann/json v3.11.3, IXWebSocket v11.4.5, and doctest v2.4.11 (tests only). Required from the system: libcurl, a threads library, and OpenSSL for IXWebSocket TLS.

The two libraries share their options and deps

Both declare SOLARI_WITH_WS and SOLARI_BUILD_TESTS, so setting either affects both. They also pin the same versions of nlohmann/json and IXWebSocket, so FetchContent de-duplicates them cleanly when you take both.

Getting Started

Create a browser session

#include <iostream>
#include <solari/browser/browser.hpp>

int main() {
  solari::browser::ClientOptions opts;
  opts.apiKey = "slr_live_...";
  solari::browser::Client client(opts);

  solari::browser::CreateSessionOptions o;
  o.stealth = true;
  o.proxy = std::string("us");

  auto session = client.sessions.create(o);
  std::cout << session.cdpEndpoint << "\n";  // drive this with a CDP client
  client.sessions.release(session.id);
}

There is no launch(). C++ has no Playwright client. See Browsers.

Create a VM

#include <solari/solari.hpp>

solari::ClientOptions opts;
opts.apiKey = "slr_live_...";
opts.baseUrl = "https://api.getsolari.com";
solari::Client client(opts);

solari::CreateSandboxOptions o;
o.template_ = "office";

// createDesktop() sends kind:"desktop"; create() stays a headless sandbox.
auto vm = client.createDesktop(o);
vm->connect();

std::cout << *vm->streamUrl() << "\n";  // wss://.../stream/<id>

// commands / files / code / git work on a VM. Mouse, keyboard, and
// screenshots do NOT exist in C++. See the VMs page.
vm->kill();

Requires the desktop entitlement, or the gateway answers 402 PlanError. There is no Desktop class: driving the GUI needs the REST API or the TypeScript SDK. Full detail on VMs.

Create a sandbox

#include <iostream>
#include <solari/solari.hpp>

int main() {
  solari::ClientOptions opts;
  opts.apiKey = "slr_live_...";
  opts.baseUrl = "https://api.getsolari.com";
  solari::Client client(opts);

  auto sbx = client.create();
  sbx->connect();

  solari::CommandOptions o;
  o.args = {"hi"};
  auto r = sbx->commands.run("echo", o);
  std::cout << r.stdout_;  // "hi"

  sbx->kill();
}

Configuration

Each library has its own ClientOptions struct, passed to its Client constructor. Neither reads an environment variable. Pass apiKey explicitly.

Field	Type	Default	Struct	Notes
`apiKey`	`std::string`	required	both	Sent as `Authorization: Bearer`. Throws if empty.
`baseUrl`	`std::string`	see notes	both	`solari::browser`: `https://api.getsolari.com`. `solari`: required, e.g. `https://api.getsolari.com`.
`maxAttempts`	`int`	`2`	`solari::browser`	Total attempts. `2` means one retry.
`backoffMs`	`long`	`500`	`solari::browser`	Fixed pause between attempts, not exponential.
`timeoutMs`	`long`	`90000`	`solari::browser`	Per attempt, not per call.
`callTimeoutMs`	`long`	`300000`	`solari`	Per-RPC timeout given to the `Sandbox` handles this client creates.

429 is never retried

Both transports retry transport errors and 5xx (the browser one only 502/503/504, with a fixed pause; the sandbox one 5xx and retryable bodies on idempotent requests, with exponential backoff + jitter). Neither retries 429. A concurrency-cap rejection needs caller-side backoff.

Reference

Class	Target	Purpose
`solari::browser::Client`	`solari_browser`	Browser control plane: `sessions`, `profiles`, proxy countries.
`solari::browser::CdpConnection`	`solari_browser`	Minimal raw-CDP escape hatch, behind `SOLARI_WITH_WS`. Not an automation API.
`solari::Client`	`solari`	Sandbox entry point: create, connect, get, kill.
`solari::Sandbox`	`solari`	A live session: commands, files, code, git.
VMs	`solari`	`createDesktop()`, `streamUrl()`, and the core namespaces. No GUI surface.
