EvolutionAPI Hosting with no per-message cost.

EvolutionAPI is a Brazilian open-source API that connects a WhatsApp account to your system (CRM, ERP, n8n, chatbots) via webhook and REST endpoints. Unlike the official Meta WhatsApp Cloud API — which charges per message after a 24h window — EvolutionAPI uses Baileys under the hood and runs on reverse-engineered WhatsApp Web, with no per-message cost. Self-hosting on Rollin Host gives you full control: your data, your sessions, your webhook, with no commercial rate limit.

Rollin Host is the leading Brazilian host for EvolutionAPI: VPS with AMD EPYC, NVMe SSD, EvolutionAPI + Docker + Traefik pre-installed by our team, and 24/7 human support in Portuguese. Unlike international providers that charge in USD and offer generic support, we deliver EvolutionAPI ready in 5–15 minutes with public SSL webhook, configured multi-instance and free migration.

At Rollin Host, EvolutionAPI plans start at R$ 52.90/month (annual) with 2 GB RAM and 1 vCore — enough for 1 active WhatsApp number. The best-selling plan (Pro) is R$ 249.90/month with 8 GB RAM and 4 vCores for up to 5 simultaneous numbers. For unlimited multi-tenant (agencies, WhatsApp SaaS), the Master plan is R$ 629.90/month with Postgres + Redis cluster. All prices already include federal taxes and the annual contract locks the price for 12 months.

WhatsApp Cloud API (official Meta) is robust, supports HSM templates and meets enterprise compliance — but charges US$ 0.008 to US$ 0.15 per message outside the 24h window, which scales to hundreds or thousands of BRL for billing or marketing operations. EvolutionAPI (unofficial, via Baileys) has a fixed cost (hosting only), sends audios, lists and buttons without template friction, and is ideal for customer service, qualified sales, reminders and support. For high volume and low criticality, EvolutionAPI is typically 10–100× cheaper.

It depends on usage (messages/min, media, webhook payload). As a reference: Inicial (2 GB) handles 1 light number. Starter (4 GB) handles 2–3 numbers. Pro (8 GB) handles 4–5 numbers with headroom. Boost (16 GB) handles 10–15 numbers. Master (32 GB) is unlimited multi-tenant with cluster — ideal for reselling agencies. We benchmark your scenario before closing the plan.

Yes. Full installation included in all plans: EvolutionAPI (latest), Docker + Docker Compose, Traefik 3.x with automatic SSL, dedicated PostgreSQL, Redis (Pro+ plans) and public webhook with own subdomain. Video onboarding session: you scan the QR code with your phone, the instance goes online, and we configure the webhook for your CRM, n8n or system.

Yes, it is the most common use case. EvolutionAPI sends webhooks to any HTTP/HTTPS URL — so it works with HubSpot, Salesforce, Pipedrive, RD Station, Bitrix24, Zoho, direct Postgres, Google Sheets, and especially n8n (which has native integration). We configure the first integration during the free onboarding.

Yes. Each instance has a unique ID, its own API key, an isolated WhatsApp session (with its own QR code) and an independent webhook. In the panel you manage all server instances (CONNECTED/DISCONNECTED status, message count, queue). An essential feature for agencies serving multiple clients on the same VPS.

Each instance fires webhooks on events: message received, message sent, read status, session connection/disconnection. You set the webhook URL in the panel, and EvolutionAPI sends POST with structured JSON payload. Automatic SSL via Traefik + Let's Encrypt — you use an HTTPS endpoint immediately, without configuring a certificate.

Yes — all media types supported: image (JPG, PNG, WebP), video (MP4), audio (OGG, MP3), document (PDF, DOC, XLS, ZIP), location, contact, sticker, lists, buttons and CTAs. Media is stored on the server (or in MinIO/S3 on Boost+ plans). The Inicial plan handles text + light media; for high media volume, we recommend Pro+.

Baileys is the core library (Node.js) that speaks the WhatsApp Web protocol. EvolutionAPI is a REST API + panel built on top of Baileys (more mature, multi-instance, persistence, queue). WPPConnect is a Python/Node alternative — also uses WhatsApp Web reverse engineering. We recommend EvolutionAPI for being more stable in production, having a clean API and a larger community. But we configure raw Baileys or WPPConnect on demand.

No — unlike the official WhatsApp Cloud API (which charges US$ 0.008+ per message), EvolutionAPI has no per-message cost. You only pay for hosting (fixed cost). Rate limit: WhatsApp has native anti-spam protections (number banning) — we recommend respecting reasonable limits: ~20 messages/min per instance and a warm-up window for new numbers.

Yes, free migration. We migrate EvolutionAPI from Hostinger VPS, DigitalOcean, AWS Lightsail, Vultr, Linode, OVH or on-premise installations. We take: active instances (with session), Postgres, media, webhook configs, API keys and domains. Window agreed with you, minimal downtime (usually 30 min to 1h per number, depending on volume).

Since your VPS is dedicated (real KVM, no multi-tenant), all conversations, media and metadata are isolated on your machine — other clients cannot access them. We apply AES-256 at rest and TLS 1.3 in transit, encrypted credential vault, access log and designated DPO.
