HollaEx vs OpenDAX: two crypto exchange kits, two different bills

Published Sep 23, 2026

Facts checked: Sep 22, 2026

Short answer

HollaEx today sells a hosted exchange: a two-week trial and an Enterprise Cloud plan at a 15% revenue share, with no self-hosting repository in its public GitHub organisation. OpenDAX is the reverse: an Apache-2.0 core you can fork, last pushed in December 2023, a user interface licensed for non-commercial use only, and a paid perpetual licence, Aurora, for production. Choose HollaEx to launch fast and share revenue, OpenDAX if your own engineers will maintain the code, and your own engine if neither maintenance model fits your plans.

What each kit is in 2026

HollaEx describes itself as "a complete crypto exchange kit" and its HollaEx Kit as exchange software that "adheres to the CCXT crypto exchange API standard"⁠[1]. Its pricing page shows two offers: an Operator Trial, free for two weeks and subject to approval, with a dedicated server and live trading, deposits and withdrawals on HollaEx cloud; and Enterprise Cloud, with unlimited users, 200+ assets, KYC and AML plugins, a market-making bot and a 15% revenue share⁠[2]. The separate on-premise pricing URL redirects to the same page with HTTP 301⁠[3].

Self-hosting now depends on code that is not publicly visible. The HollaEx CLI README describes a "CLI tool to run and interact with HollaEx Kit based exchanges" with Docker or Kubernetes and links to github.com/hollaex/hollaex-kit⁠[4]; that address returned HTTP 404 on 2026-09-22, and the hollaex organisation lists no kit repository⁠[5]. Fixed monthly prices for HollaEx appear in third-party material: AlphaPoint, a competitor, lists "Cloud Basic: $900/month" and "a free, open-source version for teams comfortable with self-hosting" in a January 2025 comparison post⁠[6]. HollaEx's own pricing page shows neither⁠[2].

OpenDAX is Openware's open-source exchange stack. Its core repository is Apache-2.0 and was last pushed on 2 December 2023; the Barong component (Apache-2.0) on 21 December 2023; Peatio (MIT) on 9 April 2023; none is archived⁠[7]⁠[8]. The BaseApp user interface "only allows Non-Commercial use": "You cannot use it for a live platform without getting a commercial license"⁠[9]. The commercial product, OpenDAX Aurora, is a "Perpetual Software License" with "only one-time payment", deployed "on your Cloud or Baremetal hosting", with "Access to Source Code"; no price is published⁠[10]. Openware says it has been "a Yellow company and a solution provider for Yellow Network" since December 2021⁠[11].

Stay with a kit if…

  1. You want a live exchange before you have an engineering team.HollaEx's trial runs trading, deposits and withdrawals live on its cloud⁠[2], and the published Enterprise Cloud price is a revenue share rather than a fixed fee.
  2. Your own engineers will maintain a fork.The OpenDAX core is Apache-2.0⁠[7], and its README asks for a minimum VM of 8 GB RAM and 4 vCPU⁠[12]. Budget a commercial UI licence or write your own front end, since BaseApp is non-commercial only⁠[9].
  3. One venue with standard spot markets is the whole plan.If your advantage is listings, community or region rather than the engine, a kit gives you the engine you do not compete on.

Consider leaving the kits if…

  1. The revenue share outgrows the platform's value to you.Symptom: the platform line grows every month you grow. At 15%⁠[2], every $100,000 of revenue in scope sends $15,000 to the vendor, month after month.
  2. Someone asks who maintains your exchange code.Symptom: a bank, an auditor or a regulator asks for the change history of the code that holds client orders, and the upstream repository was last pushed in 2023⁠[8]. On a fork, every security fix since then is yours.
  3. Your product needs what the kit does not ship.Symptom: a second venue, derivatives or a new fee model means changing an architecture your team did not design and does not fully know.

Migration path in four steps

  1. Export and reconcile.Take users, balances, deposit addresses, order and trade history and KYC references. Reconcile every internal balance against on-chain wallets before anything moves.
  2. Replay before you switch.Feed historic order flow through the new engine and compare fills and fees. Deterministic replay is how the matching engine design is tested.
  3. Move market makers first.HollaEx says its Kit adheres to the CCXT standard⁠[1]; if the new venue offers a CCXT-compatible API too, market makers' connectors change little. Give them a sandbox and a date.
  4. Cut over market by market.Announce a withdrawal window, freeze the old venue, keep its history read-only, and close the plan or the fork.

Frequently asked questions

Some libraries are: hollaex-node-lib (MIT) and hollaex-apidoc (Apache-2.0) are public in the hollaex organisation⁠[5]. The HollaEx Kit repository that the CLI links to returned 404 on 2026-09-22⁠[4], and the pricing page offers cloud plans only⁠[2].

Enterprise Cloud is a 15% revenue share with unlimited users; the two-week Operator Trial is free, subject to approval⁠[2]. Fixed monthly prices seen elsewhere, such as "$900/month", come from AlphaPoint's January 2025 comparison post⁠[6], not from HollaEx's current page.

The repository dates answer this: the core repository was last pushed on 2 December 2023, Barong on 21 December 2023 and Peatio on 9 April 2023, and none is archived⁠[8]. Openware sells Aurora with "Regular Software Maintenance"⁠[10] and describes itself as a solution provider for Yellow Network⁠[11].

The Apache-2.0 core, yes⁠[7]. The BaseApp interface, no: its licence "only allows Non-Commercial use", and a live platform needs a commercial licence from Openware⁠[9].

When the order book, the fee logic or a second venue is the business, and a revenue share or a fork you maintain alone costs more than owning a design you know.
