Five components, one stack, every layer auditable.

SDK and Platform are open. Pro adds licensed enterprise overlays. Web is your operators' UI.

FAQ

Direct answers.

Yes. Verbara is built on Asterisk PBX as its telephony substrate — we don't replace it, we modernize the operator UX, the AI pipeline, and the Pro overlays around it. If you don't have Asterisk, you deploy it alongside Verbara (one-time, well-documented setup). If you already run Asterisk, Verbara connects to your existing dialplan and config. This applies for any use-case: contact center, voice AI, omnichannel, or CPaaS.
Yes. The Platform is K8s-native — multi-tenant, multi-cluster ready in Tier 2 and up. Helm charts ship in Verbara.Sdk.Pro. You can also run it on a single VM with Docker Compose if your scale doesn't justify K8s yet — the stack is portable, no hidden cloud-only dependencies.
The OSS engine (SDK MIT + Platform Apache) keeps running indefinitely — no kill switch, no cloud check. When your license expires and the grace period ends you lose the value-add Pro features: predictive dialer, agent assist, analytics, call analytics, CSAT, event store and advanced/AI typification. What keeps the service standing is never switched off: multi-tenant, routing, realtime and clustering keep working, and so do conversations. Data and audit logs stay yours. We can't and won't disable an installation you stopped paying for; we just stop shipping new Pro releases to it.
No. The OSS edition (Tier 0) is community-supported via GitHub issues and the public Discord. Response time is best-effort. SLAs start at Tier 3 (Managed SaaS, 99.5% uptime) and Tier 4 (99.9% with 24/7 support + dedicated CSM). For self-hosted commercial tiers (1, 2), support is email or email+Slack — fast but not SLA-backed.
First-class. The default locale is es-419 (Spanish for LATAM) — verbara.io/ serves Spanish, the English version lives at /en-US/. Documentation, support, and product UI are authored in three locales (es-419, en-US, pt-BR) with parity enforced in CI. Examples in pricing, case material, and tier names lean toward LATAM contexts (BPOs, telcos). Verbara is built by people who think in Spanish.
Each solution has its own page with code, anti-positioning, and use-case-specific FAQ: contact-center for BPO/telco, voice-ai for inbound voicebots, omnichannel for WhatsApp/SMS/email, cpaas for embedded programmable telephony. Grab a Pro Developer license (Tier 0.5, free, 30 days) that unlocks every Pro feature in WarnOnly mode — evaluate the use-case that fits without commitment.
Every Verbara Platform image (api, realtime, renderer, mail, web) is cosign-signed and pinned by manifest-list digest — the exact value cosign signs. Verify any image with the public key we publish at verbara.io/keys/cosign.pub: `cosign verify --key https://verbara.io/keys/cosign.pub --insecure-ignore-tlog ghcr.io/verbara/platform/api:vX.Y.Z`. And it goes beyond the pull: your Pro license (.lic) embeds the authorized image digests (today api + realtime), so Pro features are bound to signed images by digest. A daily cron re-verifies those digests against the registry and alerts us if any one mutates.
