Developer-control AI software creation
APEX-BUILD is the developer-control AI app builder: multi-provider routing, BYOK, live per-agent cost tracking, hard budget caps, Git ownership, IDE-level control, and browser-verified full-stack builds in one workflow. Specialist agents can be assigned to the provider and model best suited to the task, with health checks, failover, and cost attribution visible during the build.
Why Apex wins
Apex isn't a prettier prompt box. It's a multi-agent production software factory with economics, architecture, and verification engineered into the workflow.
Apex makes model routing explicit and developer-controlled: each specialist agent can be assigned to the provider/model best suited to the task, with health checks, failover, and cost attribution visible during the build.
Most competitors default to managed credentials or platform-managed model access. Apex makes BYOK and managed credits first-class controls, with real-time spend visibility and per-project routing decisions.
For supported generated preview flows, Apex loads the preview in a real headless Chromium with chromedp before reporting that preview as working. We check for runtime errors, network failures, and missing assets. Competitors provide previews and deployment workflows; Apex makes explicit runtime verification a visible build gate.
Builds stream tracked token usage and cost broken down by agent role and model when providers return usage data. See which agent is spending managed credits, which provider handled it, and whether hard budget caps stopped a run before it exceeded your threshold.
Build Python data services, Go microservices, Rust systems code, Java backends, and Node/TypeScript APIs alongside React, Vue, or Svelte frontends. Lovable and Bolt are strongest around web-app workflows and JavaScript/TypeScript-oriented stacks; Apex targets broader backend generation across Python, Go, Rust, Java, Node, and TypeScript.
Inputs locked, model versions pinned, dependency graphs reproducible, every artifact hashed and traceable. Apex emphasizes staged planning, review, repair, and verification so builds can be inspected and repeated instead of treated as a one-shot prompt box.
Attach Model Context Protocol tools — Stripe, Postgres, Slack, Jira, custom HTTP — and the agents will use them as first-class capabilities, not webhook hacks. Wire secrets once and reuse them across builds.
SAML SSO, SCIM provisioning, RBAC roles, and audit logs are part of the Team and Enterprise architecture. Enterprise deployments can include single-tenant isolation, private networking, and on-prem implementation support where contracted.

Platform cockpit
Apex gives serious builders the levers they expect: context intake, model routing, MCP tools, secrets, GitHub handoff, database readiness, review gates, deploy controls, and live spend visibility in one connected workflow.
Nine specialists. One governed build.
Apex exposes a named specialist-agent architecture instead of hiding the build behind a single opaque generation stream. Each role has its own prompt pack, context window, and model assignment, and the conductor reconciles their outputs into a structured build plan.
Everything Apex ships out of the box
Transparent usage. Honest limits.
$24/mo
$59/mo
Why $59: Pro unlocks BYOK, budget controls, stronger verification, and Ollama Cloud routing options so heavy users can shift suitable agent work to lower-cost or user-owned model infrastructure while keeping Apex-managed credits available.
$149/mo
Top-up credit packs from $25 to $250. Annual plans save 20%. Enterprise deployments can include single-tenant isolation, private networking, on-prem implementation support, and procurement support where contracted.
