## Rivet.dev

At its core Rivet replaces the container per agent with an in-process primitive. An Actor runs inside your existing Node.js or Bun backend rather than in its own container or VM, which is why Rivet reports cold starts measured in single-digit milliseconds and a footprint of tens of kilobytes per Actor instead of hundreds of megabytes. Each Actor carries a SQLite database for memory, can access a filesystem and shell, sleeps when idle, and wakes with its durable state ready for the next request.

The platform handles the operational pieces teams usually build themselves: fault tolerance that reschedules Actors when a node goes down, multi-region placement that routes requests to wherever an Actor currently lives, end-to-end type safety where Actor definitions generate client types, and scheduling via cron or self-set timestamps. Storage is pulled apart into two tiers — a fast SSD for instant writes and object storage that settles writes at a fraction of the cost — so running many small databases stays affordable.

Rivet positions itself as infrastructure for the "agentic era" and can be deployed as a managed cloud, inside your own VPC through a bring-your-own-cloud model, or fully self-hosted down to air-gapped networks. It is open source under Apache 2.0, backed by Y Combinator and a16z Speedrun, and integrates with popular coding agents and frameworks.

**Pricing & Plans:** Rivet Cloud uses a plan-plus-nodes model. The control plane is Free ($0) for prototyping, Hobby at $10/month, Team at $120/month, and Enterprise at $900/month, each raising control-plane redundancy, Actor Node caps, and support. Actor Nodes are billed per month on top, from $4.20 (R-5) to $94.50 (R-160). Self-hosting is free and open source under Apache 2.0, and startups from Y Combinator or a16z Speedrun get 50% off the Team plan for 12 months.

- **Durable actors with persistent state:** Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
- **Lightweight secure sandboxing:** Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
- **Fault tolerance and workflows:** A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
- **Realtime and multiplayer:** Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
- **One-binary deployment and observability:** Ship with a single stateless Rust binary, embeds storage in S3-compatible buckets, and emits OpenTelemetry traces, metrics, and logs to your existing collector.

**Strengths:** Four-digit millisecond cold starts and a very small per-Actor memory footprint let a single server host far more agents; Open source (Apache 2.0) with a single Rust binary, so it can be self-hosted, run in a VPC, or air-gapped; Durable state via per-Actor SQLite plus object-storage-backed tiers keeps agents restart-safe and cheap; Strong developer ergonomics: typed SDKs, a React SDK, WebSocket networking, and OpenTelemetry baked in

**Limitations:** Requires Node.js or Bun and a working Rust-based control plane deployment for self-hosting, so it favors backend engineers over no-code users; Advanced durability and sandboxing concepts (Actors, WarpDrive storage) carry a learning curve; Managed cloud cost scales with Actor Nodes, which can climb for many mid-sized/sized nodes; Enterprise features like multi-tenancy and hardened compliance guidance sit behind sales conversations

## Solvely AI

Solvely AI is an all-in-one AI study platform built for students. At its core is a homework solver that accepts problems as photos, PDFs, or typed text and returns step-by-step solutions. To improve reliability, Solvely cross-checks answers across multiple top-tier AI models, and it renders explanations as visuals and short videos for subjects like 3D geometry, calculus graphing, physics force analysis, and biochemistry.

Beyond homework, Solvely targets exam preparation and everyday study. Students upload notes and past exams so the tool can predict likely topics, build mock exams and cheat sheets, and produce a daily review plan with a readiness score. It also records lectures, transcribes them, and converts the material into structured notes, flashcards, quizzes, podcasts, and other study sets, so the same source content feeds multiple study formats.

The platform reports being trusted by more than 10 million students from over 5,000 universities, with over 200 million problems solved and a 4.8-star app rating. It is available on Web, iOS, Android, and as a Chrome extension. A free tier lets students start solving immediately, while Solvely Unlimited bundles unlimited step-by-step solutions, exam prep, and other premium tools into one subscription.

**Pricing & Plans:** Freemium. Students can start for free and solve problems, while Solvely Unlimited is a paid subscription that unlocks unlimited step-by-step homework solutions, exam prep with predictions and mock exams, and additional premium study tools. Check the official pricing page for current plan details and any student discounts.

- **Multi-Model Homework Solver:** Upload a problem by photo, PDF, or text and get accurate step-by-step solutions, backed by multi-model cross-checking for higher accuracy.
- **Exam Prep & Prediction:** Upload notes and past exams to predict likely topics, generate mock exams, cheat sheets, and a daily review plan with a readiness score.
- **Notes, Flashcards & Quizzes:** Record lectures for live transcription, then auto-generate structured notes, flashcards, and quizzes from your own course materials.
- **Visual & Video Explanations:** Break down hard concepts with rendered video and visual explanations covering 3D geometry, calculus graphs, and physics simulations.
- **Cross-Platform Study:** Study wherever you are with Web, iOS, Android, and a Chrome extension, all sharing the same account and tools.

**Strengths:** Covers homework, exam prep, notes, flashcards, and quizzes in one platform; Multi-model cross-checking aims to improve answer accuracy; Visual and video explanations help with difficult STEM concepts; Available on Web, iOS, Android, and Chrome extension

**Limitations:** Unlimited access and the most powerful study features require a paid Solvely Unlimited subscription; Accuracy, while high, is not guaranteed to be 100% on every problem; The all-in-one scope means some specialized study tools may go deeper elsewhere; Best results depend on uploading clear, well-structured source material
