AlfeManaged3.3Freemium — the site describes a tenant-wide credit pool that funds compute, model usage, voice, channels, and storage, plus optional per-agent subscriptions, and is self-serve from the dashboard; no specific dollar figures or tier table are published in a verifiable form.(unverified)Managed cloud control plane, with a Sync integration backing config, files, and memory to the cloud.Built-in cross-channel memory: the Sync integration backs files, conversations, and memory to the cloud so context persists across channels.NativeVoice (Twilio + Discord), Discord, web/mobile chat, SMS + calls via Twilio, Google Workspace (Meet/Calendar/Drive), Microsoft Teams, Slack, and Sync.Nine model providers behind one proxy per Alfe's site — Anthropic, OpenAI, Gemini, DeepSeek, Mistral, xAI, OpenRouter, Zhipu, and MiniMax — with per-tenant policy and BYOK overrides.No
LangGraph PlatformFramework4.3Framework is free (MIT). Managed: Developer $0/seat (up to 5k base traces/mo), Plus $39/seat/mo, Enterprise custom; usage add-ons include deployment runs at $0.005/run.Open-source framework self-hosted on your own infra; managed cloud deployment available; self-hosted and hybrid deployment gated to the Enterprise tier.Durable execution across restarts and cold starts, persistent checkpoints (payloads up to 25 MB), and semantic search for long-term memory, with per-subagent state isolation via threads.NativeDocs cite 1000+ integrations; tools are consumed as built-ins plus remote (HTTP) and local MCP servers via langchain-mcp-adapters.Many via langchain-<provider> packages: OpenAI, Anthropic, Google (Vertex + GenAI), AWS, Ollama, Groq, Azure AI, Mistral, xAI, Cohere, DeepSeek, and more.Yes
CrewAIFramework4.0Basic is free (visual editor, AI copilot, GitHub integration, 50 workflow executions/mo). Enterprise is custom-priced (request a trial); no public figure.Hybrid — the open-source library is self-hosted via CLI; the Enterprise console offers managed deployment on CrewAI or private infrastructure.A unified Memory class where the LLM infers scope and importance on save; retrieval is ranked by similarity, recency, and importance, defaulting to LanceDB with custom backends supported.NativeConnectors including Gmail, Google Drive, Outlook, Teams, OneDrive, HubSpot, Slack, and Salesforce, plus tools to call existing CrewAI automations or Amazon Bedrock Agents.Native SDKs for OpenAI, Anthropic, Google, Azure, AWS Bedrock, and Snowflake Cortex; many more via LiteLLM (Llama, Mistral, Groq, Ollama, Perplexity, OpenRouter, and others).Yes
AutoGPTManaged3.2Managed cloud: Pro $42.50/mo and Max $272.00/mo (billed annually), with pay-as-you-go credits; no free cloud tier. Self-hosting is free.Dual — a paid managed cloud, or free self-hosting via Docker Compose.Blocks include basic operations (memory management, data structures, file I/O) and agents are file-aware; a deeper persistence model is not documented in primary sources.(unverified)NativeModular "blocks" the site describes as 45+ platforms — Google Workspace, GitHub, HubSpot, Discord, Reddit, X/Twitter, LinkedIn, Firecrawl, Perplexity, and media-generation providers.OpenAI, Anthropic (Claude), Google (Gemini), Mistral, Cohere, DeepSeek, xAI (Grok), Perplexity, Meta Llama, Qwen, Groq, Amazon Nova, and Nous Research.Yes

E2BHosting3.7Hobby (free) includes a one-time $100 usage credit, up to 1-hour sessions, and 20 concurrent sandboxes. Pro is $150/mo + usage (24-hour sessions, up to 100 concurrent). Usage is per-second (e.g. 1 vCPU at $0.000014/s).Hosted cloud that spins up on-demand secure Linux VM sandboxes reachable both internally and via a sandbox URL; self-hostable given the open-source codebase.Sandbox persistence — pausing saves both filesystem and memory state, and connect() resumes the identical state, with paused sandboxes kept indefinitely. This is infrastructure state, not agent/LLM memory.NativeFirst-party Python and JS/TS SDKs, Templates for defining environments, and MCP tools from a Docker catalog (Browserbase, Stripe, GitHub, Notion, and more).Model-agnostic — you bring your own LLM; E2B runs the code and tools, not the model.Yes

This is infrastructure state, not agent memory.PartialA Python-native SDK and CLI as the primary interface, plus Sandboxes, Notebooks, web-endpoint deployment, and observability.Not applicable — pure compute; you bring and run your own models.No
Fly.io MachinesHosting3.7Usage-based, billed per second while running (e.g. shared-cpu-1x/256MB roughly $2/mo; performance-1x/2GB roughly $32/mo). Volumes are $0.15/GB-month and egress varies by region.

Machine RAM itself is ephemeral.NativeA Machines REST API and flyctl CLI, Fly Launch for containerized deploys, and a native fly mcp command surface with client wiring for major editors.Not applicable — pure compute/hosting; commonly used to host MCP servers and AI workloads.No(unverified)
Cloudflare AgentsFramework4.5No separate charge for the SDK — you pay for underlying Workers and Durable Objects. Workers has a free tier (100k req/day) and a paid plan from $5/mo; Durable Objects bills requests, duration, and (from Jan 2026) SQLite storage.Cloudflare serverless — Workers for compute with each agent as a Durable Object; deploy once and Cloudflare runs the agents across its global network.A core strength — each agent is a Durable Object with SQLite-backed local storage, persistent memory, durable identity, and recoverable execution, with no external database required.NativeDecorator methods, state sync, scheduling, WebSockets, AI chat persistence, workflow orchestration, email/voice, browser agents, sandboxed code execution, and React hooks (useAgent, useAgentChat).Workers AI by default, plus OpenAI, Anthropic, Google Gemini, or any other provider.Yes

No separate long-term agent-memory feature is documented in primary sources.NativeBuilt-in Database and User Auth, plus connectors such as Stripe, OpenAI, BigQuery, Linear, Slack, and Notion, with more via MCP.Not named in public documentation — docs describe the Agent as powered by large language models and expose effort tiers, but no specific providers or models.(unverified)No
Vercel AI SDKSDK3.8The SDK is free and open source (MIT); you pay the underlying model/token costs of whichever provider you route to. Vercel's hosting and AI Gateway are billed separately.A self-deployed library — you install and run it inside your own app or runtime; it is not a managed service.Provides message/state and streaming primitives; built-in long-term memory and conversation persistence are left to your own store.(unverified)NativeTool calling, MCP servers and tools, structured object generation, and multimodal (text, speech, transcription, image, video) generation.Multi-provider by design — Anthropic, OpenAI, Google, xAI/Grok, Mistral, Meta, Perplexity, DeepSeek, and more (16+ providers, 100+ models).Yes
