Akka
Also known as: Akka Agentic Platform, Lightbend
Enterprise agentic AI platform that builds and runs multi agent systems on a durable distributed runtime, unifying orchestration, agents, memory, and streaming in one SDK.
Akka, formerly Lightbend, is an agentic AI platform for enterprises built on the lineage of the Akka actor toolkit, which the company says powers applications touched by more than two billion people a day. Its premise is that an entire agentic system, agents, memory, orchestration, guardrails, evaluations, and inference, runs in one runtime that already guarantees resilience and scale, so a system that compiles is ready for production.
The platform is framed as four solutions on that runtime. The Akka SDK is the component model: agents with session and durable long-term memory, durable workflows that pause for human approval and resume after crashes, autonomous agents that coordinate by delegation, handoff, and teams, timed actions and stream consumers that start work from schedules and events, and endpoints over HTTP, gRPC, MCP, A2A, and ACP.
Akka Specify turns plain-language specifications, or any of 460 use-case blueprints, into running systems. Akka Optimize routes traffic to open-weight models and trains smaller ones on the customer's data, alongside nine built-in model providers and custom ones. Akka Verify enforces guardrails and policies at runtime, escalates to human reviewers, runs evaluations inline or over a hash-chained interaction log, and maps controls to 190 AI regulations.
Teams test agents with EvalKit, which scores services against eval cases and gates regressions in CI, and red-team them with RedKit.
Akka runs self-managed on the customer's own infrastructure, in the customer's VPC, or on Akka's serverless cloud, with multi-region replication and sovereign deployments, and its trust center lists SOC 2 Type II, ISO 27001, ISO 42001, PCI DSS, and HIPAA among 50 standards. Development is free, serverless plans start at $10 a month, and self-managed production is licensed per core.
It suits engineering teams that need agentic systems with distributed-systems guarantees and governance built in; teams wanting a no-code builder will find a developer platform instead.

Integrations
Connects to any LLM and vector databases with streaming inference adapters and backpressure, exposes and consumes MCP tools, and supports MCP, A2A, and ACP inter agent protocols plus HTTP and gRPC APIs, Kafka and streaming sources, and third party brokers, agents, and systems. Integrates with existing observability stacks.
In practice
A claims process runs for days and needs a person to sign off before anything is paid. An Akka workflow pauses for an approval command and resumes where it left off, even across crashes and deployments.
Your regulators want proof of what each agent did and on whose authority. Akka keeps a hash chained log of every agent interaction with authority snapshots, and exports metrics, logs and traces over OpenTelemetry.
You need agents that react to live sensor data close to the equipment. Akka Streaming turns real time inputs such as IoT metrics, audio and video into agent work, and Akka runs self managed at the edge or in sovereign cloud regions.

Recent platform changes
Akka SDK 3.6.6 adds EvalKit, which runs agent evaluations as ordinary JUnit tests that score tool calls, arguments, replies and cost, with model judges and a minimum pass rate gate. RedKit, built on it, sends prompt injection, role play and configuration extraction attacks and fails the suite when a reply or tool call shows a breach. Cases can run against a mocked model on every build or the real model on demand, and can be drawn from recorded production interactions.

Free for development; serverless Hobby $10/mo, Priority $0.25/Akka hour; self-managed per core, custom
compute cores or platform license (not publicly disclosed)
Included quota
Hobby: 5 million requests, 250 GB storage, 1 region. Priority: 1 Akka Hour at $0.25 includes 60 minutes hosting, 25K component requests, 100 GB storage, 1 GB network transfer, 1 region, 1 service.
What is public
akka.io/pricing redirects to a page titled old-pricing that lists: free development support (commercial license for pre-production, ticket support, training); self-managed production per core per year, free for OSS, academia, startups and pre-production; Akka Automated Operations serverless plans Hobby ($10 a month), Priority ($0.25 per Akka hour) and Critical ($1.50 per hour); and Your VPC per region on custom annual pricing. The vendor's own URL label suggests the page may be superseded.
Cost watchouts
Serverless plans bill per Akka hour with request, storage and transfer allowances, so usage past the included amounts adds cost; self-managed production licenses are per core, and model inference is separate.
Variable cost rationale
Commercial licensing likely tracks compute footprint; Akka claims about one third the compute of multi runtime approaches, but no public rate card exists so exposure cannot be pinned precisely.
Sales call required
Mixed (some tiers require a call)
Free / trial
Open source BSL core available; POC offered in 48 hours
Lowest paid plan
Hobby $10/mo on Akka's serverless cloud (5 million requests, 250 GB storage, single region)
Key ambiguities
The only pricing page sits at a URL labeled old-pricing, and self-managed per core and VPC per region figures are custom.
