AltoHost replaces your entire backend service layer with 35 managed APIs behind a single key. Real-time channels, background jobs, email, cache, video, search, image processing, AI agents, AI gateway, enterprise SSO, and more — ready in minutes, not months.
Every service shares one authentication model, one dashboard, one billing account, and four official SDKs for JavaScript, Node.js, React, and AI tool integration.
The foundation of every interactive application. AltoHost gives you four real-time primitives that cover every messaging pattern — fan-out broadcasts, peer-to-peer exchanges, presence awareness, and unidirectional data streams. Every connection is secured with TLS and authenticated through HMAC-SHA256 signatures, so you can ship features with confidence.
Publish and subscribe to named channels with sub-50ms delivery worldwide. AltoHost supports public channels for broadcasts, private channels with server-side authentication, and encrypted channels where message payloads are end-to-end encrypted and never readable by the infrastructure.
Know exactly who is online in any channel. Presence channels maintain a live member list and broadcast join and leave events the instant they happen. Build typing indicators, online/offline badges, collaborative cursors, and live viewer counts without writing a single line of state management.
Let connected clients send messages directly to each other without a server round-trip. Client events are ideal for ephemeral interactions like typing indicators, cursor positions, drawing strokes, and game inputs — anywhere latency matters more than persistence.
Server-Sent Events provide a lightweight, HTTP-native way to push data from your server to connected clients. SSE streams are perfect for live feeds, log tails, progress bars, and real-time dashboards where you need unidirectional flow without the overhead of a full WebSocket connection.
Stop stitching together third-party APIs for basic backend needs. AltoHost bundles four essential platform services — job queues, caching, transactional email, and push notifications — into a single API that shares your existing authentication, rate limits, and usage dashboard. Every service is production-ready out of the box.
Offload long-running tasks to managed job queues with automatic retries, exponential backoff, configurable delays, and priority levels. Every job fires real-time progress events back to your dashboard so you can monitor execution, inspect payloads, and debug failures without tailing logs.
A fully managed key-value cache built on Redis. Store session data, API responses, feature flags, and computed results with optional TTL expiration. Reads resolve in under a millisecond, and the API supports atomic operations so you can implement counters, rate limiters, and distributed locks without a separate Redis deployment.
Send password resets, invoices, onboarding sequences, and any transactional email through a single API call. AltoHost manages deliverability, DKIM/SPF signing, bounce handling, and open/click tracking. Use built-in templates or send raw HTML — either way, emails are dispatched in under 200ms.
Reach users even when your app is closed. Send push notifications to web browsers via Web Push, and to iOS and Android via native APNs and FCM integration. Segment audiences, schedule sends, and track delivery and open rates from a unified API that works identically across every platform.
Modern applications need more than text channels. AltoHost provides fully managed video conferencing, persistent messaging, audio content hosting, and object storage — all accessible through the same API key and SDK you already use for WebSocket channels. No separate vendors, no additional billing accounts, no integration headaches.
Spin up real-time video rooms with a single API call. Each room supports up to 50 participants with adaptive bitrate streaming, screen sharing, and optional cloud recording. The AltoHost SDKs handle all WebRTC negotiation, ICE candidate exchange, and auto-reconnection so your team can focus on the product experience rather than wrestling with signalling servers.
A persistent messaging layer for chat, support, and collaboration features. Messages are stored, indexed, and retrievable with full thread support, emoji reactions, read receipts, and file attachments. Build Slack-like experiences, in-app support chat, or social feeds without designing a message schema or managing storage yourself.
Host, transcode, and stream audio files for podcasts, music, voice notes, and guided meditations. Upload in any common format and AltoHost handles transcoding to optimized streaming formats, generates waveform data, and provides playback analytics including listen duration and drop-off points.
Upload, store, and serve files of any type through a managed storage API. Generate signed upload URLs for direct client uploads, organize files into buckets, and serve content through a global CDN with automatic image optimization. Access control is enforced per-key so files inherit the same security model as the rest of your app.
Transform raw data into structured, searchable, and optimized assets. AltoHost provides four processing services that handle compute-intensive work — image manipulation, optical character recognition, full-text indexing, and media transcoding — without forcing you to provision GPU instances or manage processing pipelines.
Resize, crop, rotate, convert, watermark, and extract metadata from images via a simple API. AltoHost processes images in-memory with no temporary disk writes, supporting JPEG, PNG, WebP, AVIF, and TIFF formats. Generate thumbnails on upload, extract EXIF data, and compute dominant color palettes for dynamic UI theming.
Extract machine-readable text from photographs, scanned documents, receipts, and handwritten notes. The AltoHost OCR engine runs entirely in-process — your images never leave the infrastructure. It supports over 100 languages and returns structured output with bounding boxes, confidence scores, and paragraph segmentation.
Index documents and search them in single-digit milliseconds with typo tolerance, faceted filtering, custom ranking rules, and highlighted snippets. AltoHost search handles tokenization, stemming, and synonym expansion automatically so you get relevant results without building a search pipeline from scratch.
Transcode video and audio files between formats, compress for web delivery, extract thumbnails, and generate preview clips. Submit processing jobs through the same background jobs API and receive real-time progress events as frames are processed. Output presets cover common targets like HLS adaptive streaming, social media formats, and email-safe sizes.
Connect services, react to events, and orchestrate complex business logic without managing infrastructure. AltoHost automation tools let you design multi-step workflows visually, deploy AI agents that act on your behalf, and receive real-time HTTP callbacks whenever something important happens on your platform.
Design multi-step automation pipelines using a visual drag-and-drop builder. Chain together API calls, conditional branches, delays, loops, and data transformations into workflows that execute reliably at scale. Every run is logged with step-level timing and output so you can debug failures and optimize performance.
Deploy autonomous AI agents that orchestrate tasks, call platform APIs, process data, and make decisions on your behalf. AltoHost agents run inside your application context with full access to your channels, cache, jobs, and storage — enabling intelligent automation that goes beyond simple if/then rules.
Receive HTTP POST callbacks whenever events occur on your channels or platform services. AltoHost signs every webhook payload with HMAC-SHA256 so your server can verify authenticity. Failed deliveries are retried with exponential backoff and surfaced in the dead-letter queue for manual inspection.
Ship AI features without managing model infrastructure. AltoHost provides a unified AI gateway, version-controlled prompts, retrieval-augmented generation, automatic embedding pipelines, and full observability — all integrated with your existing channels, cache, and storage services.
A unified proxy that routes requests to OpenAI, Anthropic, Google, Mistral, and Cohere through a single API. AltoHost handles authentication, retries, and failover automatically. Enable semantic caching to serve identical queries from cache, configure fallback routing so a provider outage never breaks your app, and track cost per request across every model.
Store, version, and manage prompt templates in a centralized registry. Each prompt supports variable interpolation, revision history, and A/B testing with traffic splitting. Deploy prompt changes without code deploys, compare completion quality across variants, and roll back instantly if a new version underperforms.
Retrieval-augmented generation in a single API call. Send a query and AltoHost handles the entire pipeline — embedding the query, searching your vector collections, injecting relevant context into the prompt, and returning the LLM response. No orchestration code, no chunking logic, no prompt engineering boilerplate.
Automatically vectorize documents stored in your realtime database and sync them into your vector collections. Configure which fields to embed, choose your embedding model, and AltoHost keeps vectors in sync as documents are created, updated, or deleted — no batch jobs or manual reindexing required.
Monitor every AI request across your application with token-level, cost-level, and latency-level dashboards. Break down usage by model, provider, prompt template, and endpoint. Set budget alerts, identify slow queries, and optimize your AI spend with actionable insights — all from the AltoHost dashboard.
Security, compliance, and access control features built for teams that need enterprise-grade governance. AltoHost provides SSO, fine-grained permissions, IP restrictions, tamper-evident audit logs, and GDPR-compliant data export — all configurable per-app from the dashboard.
Enable single sign-on for your team with SAML 2.0 and OpenID Connect. AltoHost integrates with Okta, Azure Active Directory, Google Workspace, and any standards-compliant identity provider. Enforce SSO-only login, map IdP groups to AltoHost roles, and manage session policies from a central configuration.
Control access at the resource level with over 30 permission scopes. Define custom roles that specify exactly which services, apps, and actions each team member can access. Assign roles per-app or organization-wide, and audit permission changes with a complete history trail.
Restrict API access to specific IP addresses or CIDR ranges on a per-app basis. Add trusted networks for your servers, office locations, and CI/CD pipelines. Requests from non-allowlisted IPs are rejected before they reach your application logic, adding a network-level security layer.
Every action on your platform is logged in a tamper-evident, hash-chained audit trail. Configure retention policies per compliance requirement, export logs in structured formats for SOC 2, ISO 27001, and HIPAA audits, and search across millions of events with sub-second queries.
Export all of your application data in structured, machine-readable formats compliant with GDPR Article 20 (right to data portability). Schedule periodic exports or trigger one-off downloads. Exports include all service data — messages, jobs, cache entries, files, workflows, and agent runs.
Go beyond basic pub/sub with advanced real-time primitives. Stream database changes directly to WebSocket channels, enable conflict-free collaborative editing, replay missed events on reconnect, and white-label your WebSocket endpoints with custom domains.
Automatically stream database changes to WebSocket channels in real time. Configure CDC on any realtime-db collection and AltoHost will broadcast insert, update, and delete events as they happen. Build live dashboards, sync client state, and eliminate polling without writing a single line of synchronization code.
Enable real-time collaborative editing with conflict-free replicated data types backed by Yjs. Multiple users can edit the same document simultaneously with automatic conflict resolution — no operational transform complexity. AltoHost handles awareness, undo/redo history, and persistence.
Never lose events during disconnects. AltoHost stores a configurable window of channel events and replays them when a client reconnects. Specify a timestamp or event ID to resume from, and the server delivers every missed event in order before switching to live mode.
White-label your WebSocket endpoints by pointing your own domain to AltoHost infrastructure. Serve connections from ws.yourdomain.com instead of ws.altohost.com. AltoHost handles TLS certificate provisioning and renewal automatically — just add a CNAME record and you are live.
Tools that make integration smoother and debugging faster. Version your API integrations with URL-based versioning, instrument your services with OpenTelemetry, and auto-generate a GraphQL gateway from your REST endpoints.
Version your API integrations with URL-based versioning and automatic deprecation headers. AltoHost supports multiple active API versions simultaneously, gives you a migration timeline for each breaking change, and adds Sunset and Deprecation headers so your clients can prepare before old versions are retired.
Instrument your AltoHost services and export traces, metrics, and logs to any OpenTelemetry-compatible collector. AltoHost auto-instruments all API calls, WebSocket connections, job executions, and workflow runs with distributed trace context. Connect to Datadog, Grafana, Honeycomb, or any OTLP backend.
Auto-generate a GraphQL schema from your REST API endpoints. AltoHost introspects your app configuration and creates queries, mutations, and subscriptions that map directly to your services. Use a single GraphQL endpoint instead of dozens of REST calls, with built-in DataLoader batching to prevent N+1 queries.
