Standout Differences

Three different buyers, three different budgets

Buildium charges a flat monthly SaaS fee starting at $62/month capped at 150 units, Bunny bills purely on usage starting at $0.01/GB with only a $1/month account minimum, and Capacities is a freemium consumer app with Pro at $9.99/month. The pricing models alone signal how differently these products are bought and scaled.

Buildium, Bunny, Capacities

Buildium serves an entire back office, not a single workflow

Where Bunny and Capacities are point tools, Buildium bundles accounting, leasing, maintenance, and tenant screening into one operational system built specifically for real estate portfolios — a scope with no equivalent in the other two products.

Buildium

Bunny only makes sense if you're shipping infrastructure

Bunny's CDN, object storage, and edge compute products are meant to sit behind an application a developer is running. It has no note-taking or property-management analog, and its pay-as-you-go billing only pays off at real traffic volume.

Bunny

Capacities is the only one built around personal thinking, not business operations

Capacities' object-linking model targets individual knowledge work — connecting notes, people, and ideas — a fundamentally different job than running rental properties or serving web traffic.

Pros & Cons

Buildium

Pros

  • Purpose-built real estate accounting rather than adapted general small-business software
  • Backed by RealPage's resources following the 2019 acquisition, adding stability and continued investment
  • Flat-tier pricing structure is simpler to understand than older strict per-unit billing models
  • Established, widely used platform with a large existing customer base and ecosystem of integrations
  • Bundles accounting, leasing, maintenance, and payments in one system rather than requiring point solutions

Cons

  • Per-transaction add-on fees (screening, eSignatures, EFT, 1099 filing) can meaningfully raise real monthly cost above the base subscription
  • Essential tier's 150-unit cap forces an upgrade for growing portfolios sooner than the sticker price suggests
  • Enterprise pricing for portfolios above 5,000 units is not published and requires a sales call
  • Now part of a much larger corporate parent (RealPage), which may concern buyers wary of consolidation in proptech
  • Some advanced automation and API access are reserved for the top Premium tier

Bunny

Pros

  • Consumption-based pricing tends to be significantly cheaper than legacy enterprise CDNs for small and mid-sized projects
  • No long-term contracts required, with self-serve sign-up and transparent published rates
  • Free internal data transfer between Bunny Storage and Bunny CDN avoids a common hidden egress cost
  • Broad product suite (CDN, storage, streaming, image optimization, compute, DNS) covers most edge infrastructure needs in one account
  • Magic Containers lets teams run standard Docker workloads at the edge without adopting a proprietary function format

Cons

  • Usage-based pricing makes cost less predictable upfront than a fixed monthly plan for teams that prefer flat billing
  • Smaller company than hyperscale CDN competitors, which may factor into enterprise vendor risk assessments
  • Regional pricing on the Standard Network is meaningfully higher outside North America and Europe
  • Edge compute and container products are newer additions than the core CDN, with a shorter track record
  • Self-serve support model may be less suited to enterprises expecting dedicated account management by default

Capacities

Pros

  • Usable free tier with unlimited notes and objects
  • Structured object model gives more built-in organization than plain markdown notes
  • True cross-platform coverage including native mobile apps
  • No lock-in thanks to open export formats

Cons

  • Smaller plugin/integration ecosystem than more established tools like Notion or Obsidian
  • AI assistant is gated behind a paid plan
  • Learning the object-type model takes longer than starting a blank page in a simpler notes app
  • Small team size relative to larger competitors may affect roadmap pace

Use Cases

Choose Buildium: Landlords, property managers, and HOA or condo boards who need integrated accounting, leasing, maintenance, and tenant screening in one system.
Choose Bunny: Developers and engineering teams who need low-cost, usage-based CDN, storage, video streaming, or edge compute infrastructure.
Choose Capacities: Individuals building a personal knowledge base who want notes organized as linked objects rather than files and folders.

Buildium

  • Independent landlord and small portfolio management — Landlords managing a handful to a few dozen units use Buildium's Essential plan for basic accounting, leasing, and maintenance tracking.
  • Professional property management companies — Property management firms managing multiple owners' portfolios use Buildium's Growth or Premium tiers for owner reporting, trust accounting, and tenant/owner portals at scale.
  • Homeowner and condo association management — Community association managers use Buildium to handle association accounting, resident communication, and maintenance coordination.

Bunny

  • Cost-sensitive content delivery at scale — Growing SaaS companies and media sites use bunny.net's CDN to reduce bandwidth costs compared to legacy enterprise CDN providers as traffic scales.
  • Combined storage and delivery for media assets — Teams store images, videos, and static assets in Bunny Storage and serve them through Bunny CDN without paying for internal transfer between the two.
  • Edge compute for containerized workloads — Development teams deploy existing Docker-based applications to the edge via Magic Containers to reduce latency for global users without rewriting code.

Capacities

  • Personal Knowledge Management — Researchers and writers organize notes, sources, and ideas as linked objects rather than a flat file tree.
  • Daily Journaling & Task Capture — Professionals use Daily Notes to log meetings, tasks, and reflections in a structured way.

Frequently Asked Questions

Are Buildium, Bunny, and Capacities actually competitors?

No. They serve entirely different markets — Buildium is property management software for landlords and HOAs, Bunny is a developer CDN and edge platform, and Capacities is a personal note-taking app. If you're expecting a head-to-head, the honest answer is that you likely only need one of the three, and the right one depends entirely on whether your job is managing rental properties, running application infrastructure, or organizing personal notes.

Which of these is cheapest to start with?

Capacities and Bunny both let you start for close to nothing — Capacities has a free tier with Pro at $9.99/month, and Bunny's usage-based pricing has only a $1/month account minimum. Buildium is the priciest entry point at $62/month for its Essential plan, reflecting that it's built for a business (property management) rather than an individual user.

Is Buildium suitable for a single landlord with a few units?

Buildium's Essential plan is capped at 150 units, so it can technically serve a small landlord, but the $62/month starting price and its focus on accounting, leasing, and tenant-screening workflows make it best suited for landlords or property managers running enough units to justify a dedicated back-office system.

Does Bunny replace a note-taking app like Capacities?

No. Bunny is infrastructure — CDN, storage, video streaming, and edge compute meant to sit behind a website or application — while Capacities is a front-end tool for personal knowledge management. They solve unrelated problems and are typically used by different people inside the same organization.

Who owns Buildium, and does that affect the product?

Buildium has been owned by RealPage since 2019. No parent-company ownership information was documented for Bunny or Capacities.
