Comparisons / API security
RowShield vs Akto: broad API testing versus focused Supabase assurance
The short version
- Akto began as an open-source approach to API inventory and authorisation testing and has since steered its public direction heavily towards agentic-AI and MCP security. RowShield stays narrowly focused on Supabase: policies, endpoints, storage and auth settings, verified continuously from an attacker’s easiest entry point.
- Choose Akto when — your exposure involves AI agents invoking tools or MCP traffic, and you value an open-source core you can self-host.
- Choose RowShield when — your concern is a conventional Supabase database, and you want deterministic checks rooted in policy text rather than a roadmap wandering towards a different problem.
RowShield rules relevant here
Head to head: Akto vs RowShield
| Capability | Akto | RowShield | Edge |
|---|---|---|---|
| Product direction | Emphasis shifted markedly from API testing towards AI-agent and MCP traffic protection. | Stable scope centred on Postgres authorisation, unlikely to wander from it. | RowShield |
| Licensing posture | Open-source core available for self-hosting, alongside commercial tiers. | Managed service with a published scope; no operational burden handed to customers. | Akto |
| Analysis basis | Traffic capture feeding an inventory, sensitive-data classification and automated authz tests. | Direct database evaluation plus scheduled anonymous PostgREST probes. | RowShield |
| Test determinism | Coverage tracks captured traffic, so rarely exercised flows can escape testing. | Checks derive from policy text and repeat identically on every run. | RowShield |
| Supabase awareness | Treats PostgREST as one REST surface among many, without comprehending policy logic. | Built for RLS, grants, storage buckets and PostgREST semantics from the outset. | RowShield |
| Operating cost | Engineering time for collectors and triage, heavier when self-hosting the open edition. | Minimal attention after connecting; findings arrive without collector upkeep. | RowShield |
| Agent-era coverage | Actively building for agentic-AI and MCP scenarios. | Not addressed; RowShield declares the gap rather than implying coverage. | Parity |

What Akto does
Akto became known through open-source API security: capture traffic, assemble an inventory, flag sensitive data flows and run automated authorisation tests such as broken object level authorisation checks against discovered endpoints. Commercial editions extended that model.
More recently the company’s public messaging has pivoted heavily towards securing agentic AI, including Model Context Protocol traffic, positioning the platform for the emerging agent estate. Credit where due: the open-source core remains attractive to engineering-led teams, and the authorisation-testing heritage was genuine. The strategic centre of gravity has plainly moved, however, and buyers should weigh where roadmap attention now flows.
Where the scopes differ
RowShield answers one question exhaustively: what does this Supabase database permit, and has that changed? It reads the policies, probes PostgREST as the anonymous caller, and reports drift with fixes attached.
Akto answers a family of questions across an API estate, increasingly across agent traffic, none of which include evaluating a Postgres policy, because policies never traverse the wire its collectors watch. For a Supabase product that makes RowShield the specialist and Akto either a broader generalist or, given current direction, a neighbour addressing an adjacent problem altogether.
Why Supabase teams choose RowShield over Akto
Choosing a monitor means betting on attention: whichever product devotes its roadmap to your risk will serve you best. RowShield’s whole existence is the Supabase authorisation layer, so every release sharpens it. Akto’s attention now flows towards agent and MCP security, a consequential market, but one your Postgres policies did not join.
Add the practical differences, no collectors to operate, deterministic checks rooted in policy text, findings a founder can action unaided, and the case for the specialist strengthens again.
Where Akto is the right choice
Honesty cuts both ways. If your actual exposure involves AI agents invoking tools, Model Context Protocol servers, or an API estate too broad for manual review, and you prefer inspecting open source yourself, Akto’s trajectory aims directly at you and its earlier authorisation-testing craft still shows.
The fit question deserves asking rather than assuming. For a conventional Supabase product whose gravest risk is a permissive policy, agent-focused tooling solves a problem you may not yet have, while the policy problem waits unattended.
Using both
They coexist sensibly. An engineering team adopting Akto for agent-era oversight loses nothing by adding RowShield for the database layer, since neither consumes the other’s resources nor duplicates its findings. The division is clean: Akto watches novel traffic patterns as they emerge; RowShield certifies that the standing rules governing your data remain tight, and tells you precisely when they loosen.
Frequently asked
- Is RowShield affiliated with Akto?
- No. RowShield is built by Veristria and is unrelated to Akto. Any references to Akto’s name or marks belong to their owner, and this comparison relies on publicly available information gathered on 2026-08-23.
- Should we pick RowShield instead of Akto, or combine them?
- Decide by exposure. If agent and MCP traffic is your live concern, evaluate Akto for it and keep RowShield for Postgres authorisation. If your concern is the database itself, RowShield alone covers that ground without collector overhead.
- Is Akto still focused on traditional API security?
- Its origins lie in open-source API inventory and authorisation testing, but its current public emphasis sits squarely on agentic-AI and MCP security. Supabase-specific row level security coverage was never its centre of gravity and is unlikely to become it.
