Stacker Alternatives: 8 honest options, sorted by use case

Stacker built its name as the way to turn an Airtable base into a branded, login-gated portal. That is no longer what the company sells. Over the last two years Stacker has repositioned around a native database, AI app generation, and most recently AI agents. Its live pricing page now leads with an AI agents product from $50 per month, and the standalone portal product is no longer publicly priced. Airtable still works, but through a sync that copies your base into Stacker's own database, not a live connection.

If you are on Stacker for the Airtable portal and that direction does not match what you need, you are not stuck. Your data is in Airtable, so switching is a rebuild of the portal, not a migration of the database. This post covers eight alternatives and, more usefully, sorts them by what you were actually building, because the right answer for a client portal is not the right answer for an internal admin tool.

CollabPortals is one of those alternatives and it is the product behind this blog. We sit at the lightweight-portal end: flat pricing, Airtable-only, live connection, no app builder. I have tried to write about the other seven the way I would want someone to write about mine: accurately, and pointing you elsewhere when elsewhere is the better fit.

If you want the direct head to head, the CollabPortals vs Stacker page covers that comparison on its own.

Why people are leaving Stacker

The reasons show up consistently across reviews, Reddit threads, and migration posts:

• The product moved on from Airtable portals. Stacker's headline is now AI agents and a native database. The Airtable portal you signed up for still exists, but it is no longer the center of the roadmap.
• Portal pricing is now opaque. The old published portal tiers are gone from the live site. What you see today is the AI agents plan from $50 per month, with the portal product pointing to a sales conversation. Buyers do not like quoting against a moving target.
• It syncs Airtable, it does not read it live. Stacker copies your base into its own database through Data Sync. That means a second copy of your data to keep consistent, and changes that land on a sync cycle rather than instantly.
• The platform keeps changing shape. Classic, then a native-tables version, then an AI rebrand, now agents. Several pivots in a short window, from a small team, makes long-term commitment to any one feature set hard to count on.
• Price for small teams. Even on the older portal tiers, the common complaint was that the cost was high relative to the feature set once you needed Airtable and removed branding.

None of this makes Stacker a bad product. It makes it a different product than the Airtable portal tool many people bought.

Two things to watch beyond the sticker price

Setup time. Most tools below are app builders, not portals. They can be cheaper on paper, but you spend the saving back in setup, because you are building a portal on a blank canvas rather than configuring one that already exists. A purpose-built portal tool gets you live in minutes.

The data model. Stacker copies your Airtable data into its own database. Some alternatives do the same; others read Airtable directly. A direct, live connection means one copy of the truth, no sync lag, and nothing extra to manage. A sync model means a second store that can drift. Decide which you want before you pick.

The alternatives

CollabPortals (collabportals.com)

Disclosure: this is our product, so read it with that in mind. CollabPortals is the lightweight portal option here: $10 per month flat, Airtable-only, with unlimited portals and unlimited end users. You connect Airtable via OAuth, pick the tables and fields to expose, set table, field, and role permissions, and share a portal URL. End users sign in with their email and a 6-digit code, so nobody needs an Airtable seat. You can brand the portal with your own logo and serve it on your own custom domain.

The key difference from Stacker is the data model. CollabPortals reads and writes your Airtable base directly, with no copy and no separate database. Your base stays the single source of truth and changes show up immediately. There is no page builder, no workflow engine, and no AI. If all you need is a permissioned portal onto Airtable, you are done on day one. For anything broader, pick something further down.

Best for: small teams, agencies, and operators who want a live Airtable portal that is ready in minutes, with external users interacting with the data and no per-seat fees.

Noloco (noloco.io)

Noloco is the closest like-for-like replacement for Stacker, and the most common destination for teams leaving it. It connects to Airtable, SmartSuite, and SQL databases, and pairs that with true record-level and field-level permissions, a workflow automation engine, and native Stripe payments. Pricing is Free to start, $99 per month on Pro (billed annually, $149 month to month), and $213 per month on Business (annually, $319 monthly), with cheap client seats bundled on top of the team seats.

If your reason for leaving Stacker is that you want more than a portal, workflows, payments, or the option to move off Airtable onto Postgres later, Noloco covers that ground without the constant repositioning.

Best for: agencies and professional services teams that need client portals with workflow logic and payments, not just data views.

Softr (softr.io)

Softr is the most popular and most beginner-friendly portal and app builder. It has a large block and template library, connects to Airtable and many other sources, and includes native forms and Stripe. It has a real free tier (10 app users), then Basic at $49 per month (20 users), Professional at $139 (100 users), and Business at $269 (500 users), with per-user overages between tiers. One caveat for permission-heavy portals: field-level permissions are not generally available, so you cannot hide individual fields per user group today.

Best for: teams that want the richest block builder and template library, and are happy to assemble pages rather than configure a ready-made portal. See CollabPortals vs Softr for the lightweight-portal contrast.

Pory (pory.io)

Pory is Airtable-only and prices per portal. Professional is $99 per month for one portal with unlimited end users and up to 5 collaborators, and the Unlimited plan at $549 per month removes the per-portal cap. That model suits an agency running many separate branded portals, where per-portal isolation and unlimited users per portal are the point.

Best for: agencies and consultants running multiple separate branded client portals in parallel. CollabPortals vs Pory puts the two Airtable portal builders side by side.

Glide (glideapps.com)

Glide is the mobile-first option. It produces polished, app-like progressive web apps and is one of the smoothest drag-and-drop experiences around. The catch for Airtable users is that Airtable as a data source is gated to the Business plan at $199 per month (billed yearly), which includes 30 users and then charges per user above that. Apps are PWAs, so there is no App Store path.

Best for: mobile-first apps and field tools where UI polish matters more than a live Airtable connection. CollabPortals vs Glide covers the difference in scope.

Knack (knack.com)

Knack is not an Airtable front end. It is a native database app builder: you build or import your data onto Knack's own database rather than connecting Airtable. In return you get mature roles and permissions, reporting, e-commerce, and unlimited end users with no per-user fees. Plans run from $59 per month (Starter) to $130 (Pro) and $300 (Corporate). HIPAA with a signed BAA is available, but only through the separate Knack Health line from $625 per month.

Best for: teams ready to leave Airtable and own a native database, or anyone who needs HIPAA-grade compliance for sensitive records.

Jet Admin (jetadmin.io)

Jet Admin reaches deeper into admin-panel territory than portal territory. It connects to 30+ backends including SQL, REST, Firebase, and Airtable. Internal tools start at $39 per month, but the customer-portal line is priced per end user, at $24 per user per month on Starter and $48 on Pro, so portal cost scales linearly with audience size.

Best for: larger teams that need one builder for internal admin tools and external portals across several databases, and whose portal audience is small enough that per-user pricing still works.

Airtable Interfaces (airtable.com/interfaces)

Interfaces is built into Airtable on any paid plan. You can build dashboards and simple pages directly on top of your base with no extra tool. For internal teams where every user already has an Airtable seat, it is the zero-overhead option. It is a poor fit for external users, because every editor still needs an Airtable seat, which puts you back onto per-seat pricing.

Best for: internal-only dashboards for teams that already pay for Airtable. CollabPortals vs Airtable Interfaces covers when the built-in option is enough.

What to pick, by use case

This is the part that matters. Stacker was used for a lot of different jobs, and the best replacement depends on which one you were doing.

• Client portals (agencies, consultants, freelancers giving each client a branded login): CollabPortals if your data is in Airtable and you want a flat-priced, live portal that is ready in minutes. Noloco if you also need workflow automation or payments. See client portals and freelancer portals.
• Customer self-service portals (orders, bookings, downloads): Softr for the richest blocks and Stripe checkout, or CollabPortals for a cheaper, simpler login portal on Airtable.
• CRM and account management (each rep or tutor sees only their records): CollabPortals for the scoped-login-on-Airtable pattern at a flat price, Noloco when the deal flow needs automation. See CRM portals and sales rep portals.
• Project and task tracking shared with clients or stakeholders: CollabPortals for a branded portal on the Airtable base you already keep, Noloco if approvals and notifications matter. See project management portals.
• Internal operations and admin tools: Jet Admin or Retool for logic-heavy internal consoles across several databases; CollabPortals for the lighter case of giving staff a permissioned view onto Airtable. See internal request portals.
• Membership and community directories: Softr for richer member and directory blocks; CollabPortals when the membership data is in Airtable and you want a simple branded login. See membership management portals.
• Student and cohort portals: Softr for a public course site plus a private area, or CollabPortals when each student should see only their own records. See student portals.
• Nonprofit and case management: Knack if the data is sensitive and needs HIPAA, Noloco for workflow-heavy case management, CollabPortals for budget-constrained Airtable nonprofits with non-regulated data. See nonprofit portals.
• Inventory and catalog portals: Softr or CollabPortals for a branded, login-gated view onto Airtable stock or products, read live. See inventory management portals.
• A real app, not a portal (heavy logic, automation, native database, AI generation): Noloco, Knack, or Glide, depending on whether you need workflows, a native database, or mobile.

Three questions usually decide it: portal or full app, live Airtable or a synced copy, and flat or per-user pricing. If the answer is portal, live, and flat, CollabPortals is built for that case. If you need a full app and are happy to invest the setup time, one of the broader tools fits better.

When CollabPortals is not the right fit

CollabPortals does one thing: a branded, permissioned portal on a live Airtable base. It is not the answer if your data is not in Airtable, if you want to own a native or SQL database, if you need workflow automation, in-portal payments, AI generation, SSO, or a native mobile app, or if you need HIPAA compliance. For those, the tools above are the honest recommendation. If a live Airtable portal with flat pricing is what you came to Stacker for, that is exactly the gap we fill.

Frequently asked questions

Is Stacker discontinuing Airtable support?

Not formally, but Airtable is no longer the focus. Stacker has repositioned around a native database, AI app generation, and AI agents. Airtable still works through Stacker's Data Sync, which copies your base into Stacker's own database and keeps it in sync, rather than reading Airtable directly. If you chose Stacker specifically to put a portal on a live Airtable base, that is the part of the product the company has moved away from.

Is Stacker the same as StackAI?

No. Stacker (stacker.ai, formerly stackerhq.com) is the Airtable portal and app builder covered here. StackAI (stackai.com) is a separate AI company. They are unrelated.

What is the cheapest Stacker alternative for an Airtable client portal?

CollabPortals at $10 per month flat, with unlimited end users and unlimited portals. Pory is unlimited end users too but is priced per portal at $99 per month. Airtable Interfaces is the cheapest if every user already has an Airtable seat, but it is a poor fit for external users because each one needs a seat.

Which Stacker alternative reads Airtable live instead of syncing it?

CollabPortals reads and writes your Airtable base directly through the Airtable API, with no copy and no separate database. Stacker, by contrast, syncs your data into its own store. If you want the portal to always reflect the true live state of your base, a direct connection avoids sync lag and duplicate data.

What is the best Stacker alternative if I need more than a portal?

Noloco if you need workflow automation, payments, and the option to move off Airtable onto SQL later. Knack if you want to own a native database with HIPAA available. Jet Admin if you are building internal admin tools across several backends. CollabPortals is deliberately narrower: a portal, not an app builder.
